Export action

#Introduction

Filament includes an action that is able to export rows to a CSV or XLSX file. When the trigger button is clicked, a modal asks for the columns that they want to export, and what they should be labeled. This feature uses job batches and database notifications, so you need to publish those migrations from Laravel. Also, you need to publish the migrations for tables that Filament uses to store information about exports:

# Laravel 11 and higher
php artisan make:queue-batches-table
php artisan make:notifications-table

# Laravel 10
php artisan queue:batches-table
php artisan notifications:table

# All apps
php artisan vendor:publish --tag=filament-actions-migrations
php artisan migrate

You may use the ExportAction like so:

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportAction;

ExportAction::make()
    ->exporter(ProductExporter::class)

If you want to add this action to the header of a table, you may do so like this:

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportAction;
use Filament\Tables\Table;

public function table(Table $table): Table
{
    return $table
        ->headerActions([
            ExportAction::make()
                ->exporter(ProductExporter::class),
        ]);
}

Or if you want to add it as a table bulk action, so that the user can choose which rows to export, they can use Filament\Actions\ExportBulkAction:

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportBulkAction;
use Filament\Tables\Table;

public function table(Table $table): Table
{
    return $table
        ->bulkActions([
            ExportBulkAction::make()
                ->exporter(ProductExporter::class),
        ]);
}

The “exporter” class needs to be created to tell Filament how to export each row.

#Creating an exporter

To create an exporter class for a model, you may use the make:filament-exporter command, passing the name of a model:

php artisan make:filament-exporter Product

This will create a new class in the app/Filament/Exports directory. You now need to define the columns that can be exported.

#Automatically generating exporter columns

If you’d like to save time, Filament can automatically generate the columns for you, based on your model’s database columns, using --generate:

php artisan make:filament-exporter Product --generate

#Defining exporter columns

To define the columns that can be exported, you need to override the getColumns() method on your exporter class, returning an array of ExportColumn objects:

use Filament\Actions\Exports\ExportColumn;

public static function getColumns(): array
{
    return [
        ExportColumn::make('name'),
        ExportColumn::make('sku')
            ->label('SKU'),
        ExportColumn::make('price'),
    ];
}

#Customizing the label of an export column

The label for each column will be generated automatically from its name, but you can override it by calling the label() method:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('sku')
    ->label('SKU')

#Configuring the default column selection

By default, all columns will be selected when the user is asked which columns they would like to export. You can customize the default selection state for a column with the enabledByDefault() method:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('description')
    ->enabledByDefault(false)

#Disabling column selection

By default, user will be asked which columns they would like to export. You can disable this functionality using columnMapping(false):

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportAction;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->columnMapping(false)

#Calculated export column state

Sometimes you need to calculate the state of a column, instead of directly reading it from a database column.

By passing a callback function to the state() method, you can customize the returned state for that column based on the $record:

use App\Models\Order;
use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('amount_including_vat')
    ->state(function (Order $record): float {
        return $record->amount * (1 + $record->vat_rate);
    })

As well as $record, the state() function can inject various utilities as parameters.

Utility	Type	Parameter	Description
Export column	Filament\Actions\Exports\ExportColumn	$column	The current export column instance.
Exporter	?Filament\Actions\Exports\Exporter	$exporter	The instance of the exporter class that is currently being used for exporting data.
Options	array<string, mixed>	$options	The options that were defined when the export started.
Eloquent record	?Illuminate\Database\Eloquent\Model	$record	The Eloquent record that is currently being exported.

#Formatting the value of an export column

You may instead pass a custom formatting callback to formatStateUsing(), which accepts the $state of the cell, and optionally the Eloquent $record:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('status')
    ->formatStateUsing(fn (string $state): string => __("statuses.{$state}"))

As well as $state, the formatStateUsing() function can inject various utilities as parameters.

Utility	Type	Parameter	Description
Export column	Filament\Actions\Exports\ExportColumn	$column	The current export column instance.
Exporter	?Filament\Actions\Exports\Exporter	$exporter	The instance of the exporter class that is currently being used for exporting data.
Options	array<string, mixed>	$options	The options that were defined when the export started.
Eloquent record	?Illuminate\Database\Eloquent\Model	$record	The Eloquent record that is currently being exported.
State	mixed	$state	The state to format.

If there are multiple values in the column, the function will be called for each value.

#Limiting text length

You may limit() the length of the cell’s value:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('description')
    ->limit(50)

As well as allowing a static value, the limit() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.

Utility	Type	Parameter	Description
Export column	Filament\Actions\Exports\ExportColumn	$column	The current export column instance.
Exporter	?Filament\Actions\Exports\Exporter	$exporter	The instance of the exporter class that is currently being used for exporting data.
Options	array<string, mixed>	$options	The options that were defined when the export started.
Eloquent record	?Illuminate\Database\Eloquent\Model	$record	The Eloquent record that is currently being exported.

#Limiting word count

You may limit the number of words() displayed in the cell:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('description')
    ->words(10)

As well as allowing a static value, the words() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.

Utility	Type	Parameter	Description
Export column	Filament\Actions\Exports\ExportColumn	$column	The current export column instance.
Exporter	?Filament\Actions\Exports\Exporter	$exporter	The instance of the exporter class that is currently being used for exporting data.
Options	array<string, mixed>	$options	The options that were defined when the export started.
Eloquent record	?Illuminate\Database\Eloquent\Model	$record	The Eloquent record that is currently being exported.

#Adding a prefix or suffix

You may add a prefix() or suffix() to the cell’s value:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('domain')
    ->prefix('https://')
    ->suffix('.com')

As well as allowing static values, the prefix() and suffix() methods also accept functions to dynamically calculate them. You can inject various utilities into the functions as parameters.

Utility	Type	Parameter	Description
Export column	Filament\Actions\Exports\ExportColumn	$column	The current export column instance.
Exporter	?Filament\Actions\Exports\Exporter	$exporter	The instance of the exporter class that is currently being used for exporting data.
Options	array<string, mixed>	$options	The options that were defined when the export started.
Eloquent record	?Illuminate\Database\Eloquent\Model	$record	The Eloquent record that is currently being exported.

#Exporting multiple values in a cell

By default, if there are multiple values in the column, they will be comma-separated. You may use the listAsJson() method to list them as a JSON array instead:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('tags')
    ->listAsJson()

#Displaying data from relationships

You may use “dot notation” to access columns within relationships. The name of the relationship comes first, followed by a period, followed by the name of the column to display:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('author.name')

#Counting relationships

If you wish to count the number of related records in a column, you may use the counts() method:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('users_count')
    ->counts('users')

In this example, users is the name of the relationship to count from. The name of the column must be users_count, as this is the convention that Laravel uses for storing the result.

If you’d like to scope the relationship before calculating, you can pass an array to the method, where the key is the relationship name and the value is the function to scope the Eloquent query with:

use Filament\Actions\Exports\ExportColumn;
use Illuminate\Database\Eloquent\Builder;

ExportColumn::make('users_count')
    ->counts([
        'users' => fn (Builder $query) => $query->where('is_active', true),
    ])

#Determining relationship existence

If you simply wish to indicate whether related records exist in a column, you may use the exists() method:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('users_exists')
    ->exists('users')

In this example, users is the name of the relationship to check for existence. The name of the column must be users_exists, as this is the convention that Laravel uses for storing the result.

If you’d like to scope the relationship before calculating, you can pass an array to the method, where the key is the relationship name and the value is the function to scope the Eloquent query with:

use Filament\Actions\Exports\ExportColumn;
use Illuminate\Database\Eloquent\Builder;

ExportColumn::make('users_exists')
    ->exists([
        'users' => fn (Builder $query) => $query->where('is_active', true),
    ])

#Aggregating relationships

Filament provides several methods for aggregating a relationship field, including avg(), max(), min() and sum(). For instance, if you wish to show the average of a field on all related records in a column, you may use the avg() method:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('users_avg_age')
    ->avg('users', 'age')

In this example, users is the name of the relationship, while age is the field that is being averaged. The name of the column must be users_avg_age, as this is the convention that Laravel uses for storing the result.

If you’d like to scope the relationship before calculating, you can pass an array to the method, where the key is the relationship name and the value is the function to scope the Eloquent query with:

use Filament\Actions\Exports\ExportColumn;
use Illuminate\Database\Eloquent\Builder;

ExportColumn::make('users_avg_age')
    ->avg([
        'users' => fn (Builder $query) => $query->where('is_active', true),
    ], 'age')

#Configuring the export formats

By default, the export action will allow the user to choose between both CSV and XLSX formats. You can use the ExportFormat enum to customize this, by passing an array of formats to the formats() method on the action:

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportAction;
use Filament\Actions\Exports\Enums\ExportFormat;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->formats([
        ExportFormat::Csv,
    ])
    // or
    ->formats([
        ExportFormat::Xlsx,
    ])
    // or
    ->formats([
        ExportFormat::Xlsx,
        ExportFormat::Csv,
    ])

Alternatively, you can override the getFormats() method on the exporter class, which will set the default formats for all actions that use that exporter:

use Filament\Actions\Exports\Enums\ExportFormat;

public function getFormats(): array
{
    return [
        ExportFormat::Csv,
    ];
}

#Modifying the export query

By default, if you are using the ExportAction with a table, the action will use the table’s currently filtered and sorted query to export the data. If you don’t have a table, it will use the model’s default query. To modify the query builder before exporting, you can use the modifyQueryUsing() method on the action:

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportAction;
use Illuminate\Database\Eloquent\Builder;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->modifyQueryUsing(fn (Builder $query) => $query->where('is_active', true))

You may inject the $options argument into the function, which is an array of options for that export:

use App\Filament\Exports\ProductExporter;
use Illuminate\Database\Eloquent\Builder;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->modifyQueryUsing(fn (Builder $query, array $options) => $query->where('is_active', $options['isActive'] ?? true))

Alternatively, you can override the modifyQuery() method on the exporter class, which will modify the query for all actions that use that exporter:

use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Relations\MorphTo;

public static function modifyQuery(Builder $query): Builder
{
    return $query->with([
        'purchasable' => fn (MorphTo $morphTo) => $morphTo->morphWith([
            ProductPurchase::class => ['product'],
            ServicePurchase::class => ['service'],
            Subscription::class => ['plan'],
        ]),
    ]);
}

#Configuring the export filesystem

#Customizing the storage disk

By default, exported files will be uploaded to the storage disk defined in the configuration file, which is public by default. You can set the FILAMENT_FILESYSTEM_DISK environment variable to change this.

While using the public disk a good default for many parts of Filament, using it for exports would result in exported files being stored in a public location. As such, if the default filesystem disk is public and a local disk exists in your config/filesystems.php, Filament will use the local disk for exports instead. If you override the disk to be public for an ExportAction or inside an exporter class, Filament will use that.

In production, you should use a disk such as s3 with a private access policy, to prevent unauthorized access to the exported files.

If you want to use a different disk for a specific export, you can pass the disk name to the disk() method on the action:

use Filament\Actions\ExportAction;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->fileDisk('s3')

You may set the disk for all export actions at once in the boot() method of a service provider such as AppServiceProvider:

use Filament\Actions\ExportAction;

ExportAction::configureUsing(fn (ExportAction $action) => $action->fileDisk('s3'));

Alternatively, you can override the getFileDisk() method on the exporter class, returning the name of the disk:

public function getFileDisk(): string
{
    return 's3';
}

Export files that are created are the developer’s responsibility to delete if they wish. Filament does not delete these files in case the exports need to be downloaded again at a later date.

#Configuring the export file names

By default, exported files will have a name generated based on the ID and type of the export. You can also use the fileName() method on the action to customize the file name:

use Filament\Actions\ExportAction;
use Filament\Actions\Exports\Models\Export;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->fileName(fn (Export $export): string => "products-{$export->getKey()}.csv")

Alternatively, you can override the getFileName() method on the exporter class, returning a string:

use Filament\Actions\Exports\Models\Export;

public function getFileName(Export $export): string
{
    return "products-{$export->getKey()}.csv";
}

#Using export options

The export action can render extra form components that the user can interact with when exporting a CSV. This can be useful to allow the user to customize the behavior of the exporter. For instance, you might want a user to be able to choose the format of specific columns when exporting. To do this, you can return options form components from the getOptionsFormComponents() method on your exporter class:

use Filament\Forms\Components\TextInput;

public static function getOptionsFormComponents(): array
{
    return [
        TextInput::make('descriptionLimit')
            ->label('Limit the length of the description column content')
            ->integer(),
    ];
}

Alternatively, you can pass a set of static options to the exporter through the options() method on the action:

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportAction;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->options([
        'descriptionLimit' => 250,
    ])

As well as allowing a static value, the options() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.

Utility	Type	Parameter	Description
Action	Filament\Actions\Action	$action	The current action instance.
Arguments	array<string, mixed>	$arguments	The array of arguments passed to the action when it was triggered.
Data	array<string, mixed>	$data	The array of data submitted from form fields in the action's modal. It will be empty before the modal form is submitted.
Livewire	Livewire\Component	$livewire	The Livewire component instance.
Eloquent model FQN	?string<Illuminate\Database\Eloquent\Model>	$model	The Eloquent model FQN for the current action, if one is attached.
Mounted actions	array<Filament\Actions\Action>	$mountedActions	The array of actions that are currently mounted in the Livewire component. This is useful for accessing data from parent actions.
Eloquent record	?Illuminate\Database\Eloquent\Model	$record	The Eloquent record for the current action, if one is attached.
Schema	Filament\Schemas\Schema	$schema	[Actions in schemas only] The schema object that this action belongs to.
Schema component	Filament\Schemas\Components\Component	$schemaComponent	[Actions in schemas only] The schema component that this action belongs to.
Schema component state	mixed	$schemaComponentState	[Actions in schemas only] The current value of the schema component.
Schema get function	Filament\Schemas\Components\Utilities\Get	$schemaGet	[Actions in schemas only] A function for retrieving values from the schema data. Validation is not run on form fields.
Schema operation	string	$schemaOperation	[Actions in schemas only] The current operation being performed by the schema. Usually create, edit, or view.
Schema set function	Filament\Schemas\Components\Utilities\Set	$schemaSet	[Actions in schemas only] A function for setting values in the schema data.
Selected Eloquent records	Illuminate\Support\Collection	$selectedRecords	[Bulk actions only] The Eloquent records selected in the table.
Table	Filament\Tables\Table	$table	[Actions in tables only] The table object that this action belongs to.

Now, you can access the data from these options inside the exporter class, by injecting the $options argument into any closure function. For example, you might want to use it inside formatStateUsing() to format a column’s value:

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('description')
    ->formatStateUsing(function (string $state, array $options): string {
        return (string) str($state)->limit($options['descriptionLimit'] ?? 100);
    })

Alternatively, since the $options argument is passed to all closure functions, you can access it inside limit():

use Filament\Actions\Exports\ExportColumn;

ExportColumn::make('description')
    ->limit(fn (array $options): int => $options['descriptionLimit'] ?? 100)

#Using a custom user model

By default, the exports table has a user_id column. That column is constrained to the users table:

$table->foreignId('user_id')->constrained()->cascadeOnDelete();

In the Export model, the user() relationship is defined as a BelongsTo relationship to the App\Models\User model. If the App\Models\User model does not exist, or you want to use a different one, you can bind a new Authenticatable model to the container in a service provider’s register() method:

use App\Models\Admin;
use Illuminate\Contracts\Auth\Authenticatable;

$this->app->bind(Authenticatable::class, Admin::class);

If your authenticatable model uses a different table to users, you should pass that table name to constrained():

$table->foreignId('user_id')->constrained('admins')->cascadeOnDelete();

#Using a polymorphic user relationship

If you want to associate exports with multiple user models, you can use a polymorphic MorphTo relationship instead. To do this, you need to replace the user_id column in the exports table:

$table->morphs('user');

Then, in a service provider’s boot() method, you should call Export::polymorphicUserRelationship() to swap the user() relationship on the Export model to a MorphTo relationship:

use Filament\Actions\Exports\Models\Export;

Export::polymorphicUserRelationship();

#Limiting the maximum number of rows that can be exported

To prevent server overload, you may wish to limit the maximum number of rows that can be exported from one CSV file. You can do this by calling the maxRows() method on the action:

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportAction;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->maxRows(100000)

#Changing the export chunk size

Filament will chunk the CSV, and process each chunk in a different queued job. By default, chunks are 100 rows at a time. You can change this by calling the chunkSize() method on the action:

use App\Filament\Exports\ProductExporter;
use Filament\Actions\ExportAction;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->chunkSize(250)

As well as allowing a static value, the chunkSize() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.

#Changing the CSV delimiter

The default delimiter for CSVs is the comma (,). If you want to export using a different delimiter, you may override the getCsvDelimiter() method on the exporter class, returning a new one:

public static function getCsvDelimiter(): string
{
    return ';';
}

As well as allowing a static value, the csvDelimiter() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.

#Customizing XLSX files

If you want to style the cells of the XLSX file, you may override the getXlsxCellStyle() method on the exporter class, returning an OpenSpout Style object:

use OpenSpout\Common\Entity\Style\Style;

public function getXlsxCellStyle(): ?Style
{
    return (new Style())
        ->setFontSize(12)
        ->setFontName('Consolas');
}

If you want to use a different style for the header cells of the XLSX file only, you may override the getXlsxHeaderCellStyle() method on the exporter class, returning an OpenSpout Style object:

use OpenSpout\Common\Entity\Style\CellAlignment;
use OpenSpout\Common\Entity\Style\CellVerticalAlignment;
use OpenSpout\Common\Entity\Style\Color;
use OpenSpout\Common\Entity\Style\Style;

public function getXlsxHeaderCellStyle(): ?Style
{
    return (new Style())
        ->setFontBold()
        ->setFontItalic()
        ->setFontSize(14)
        ->setFontName('Consolas')
        ->setFontColor(Color::rgb(255, 255, 77))
        ->setBackgroundColor(Color::rgb(0, 0, 0))
        ->setCellAlignment(CellAlignment::CENTER)
        ->setCellVerticalAlignment(CellVerticalAlignment::CENTER);
}

Alternatively, if you want to pass “options” to the OpenSpout XLSX Writer, you can return an OpenSpout\Writer\XLSX\Options instance from the getXlsxWriterOptions() method of the exporter class:

use OpenSpout\Writer\XLSX\Options;

public function getXlsxWriterOptions(): ?Options
{
    $options = new Options();
    $options->setColumnWidth(10, 1);
    $options->setColumnWidthForRange(12, 2, 3);
    
    return $options;
}

If you want to customize the XLSX writer before it is closed, you can override the configureXlsxWriterBeforeClosing() method on the exporter class. This method receives the Writer instance as a parameter, and you can modify it before it is closed:

use OpenSpout\Writer\XLSX\Entity\SheetView;
use OpenSpout\Writer\XLSX\Writer;

public function configureXlsxWriterBeforeClose(Writer $writer): Writer
{
    $sheetView = new SheetView();
    $sheetView->setFreezeRow(2);
    $sheetView->setFreezeColumn('B');
    
    $sheet = $writer->getCurrentSheet();
    $sheet->setSheetView($sheetView);
    $sheet->setName('export');
    
    return $writer;
}

#Customizing the export job

The default job for processing exports is Filament\Actions\Exports\Jobs\PrepareCsvExport. If you want to extend this class and override any of its methods, you may replace the original class in the register() method of a service provider:

use App\Jobs\PrepareCsvExport;
use Filament\Actions\Exports\Jobs\PrepareCsvExport as BasePrepareCsvExport;

$this->app->bind(BasePrepareCsvExport::class, PrepareCsvExport::class);

Or, you can pass the new job class to the job() method on the action, to customize the job for a specific export:

use App\Filament\Exports\ProductExporter;
use App\Jobs\PrepareCsvExport;
use Filament\Actions\ExportAction;

ExportAction::make()
    ->exporter(ProductExporter::class)
    ->job(PrepareCsvExport::class)

#Customizing the export queue and connection

By default, the export system will use the default queue and connection. If you’d like to customize the queue used for jobs of a certain exporter, you may override the getJobQueue() method in your exporter class:

public function getJobQueue(): ?string
{
    return 'exports';
}

You can also customize the connection used for jobs of a certain exporter, by overriding the getJobConnection() method in your exporter class:

public function getJobConnection(): ?string
{
    return 'sqs';
}

#Customizing the export job middleware

By default, the export system will only process one job at a time from each export. This is to prevent the server from being overloaded, and other jobs from being delayed by large exports. That functionality is defined in the WithoutOverlapping middleware on the exporter class:

public function getJobMiddleware(): array
{
    return [
        (new WithoutOverlapping("export{$this->export->getKey()}"))->expireAfter(600),
    ];
}

If you’d like to customize the middleware that is applied to jobs of a certain exporter, you may override this method in your exporter class. You can read more about job middleware in the Laravel docs.

#Customizing the export job retries

By default, the export system will retry a job for 24 hours, or until it fails with 5 unhandled exceptions, whichever happens first. This is to allow for temporary issues, such as the database being unavailable, to be resolved. You may change the time period for the job to retry, which is defined in the getJobRetryUntil() method on the exporter class:

use Carbon\CarbonInterface;

public function getJobRetryUntil(): ?CarbonInterface
{
    return now()->addHours(12);
}

You can read more about job retries in the Laravel docs.

#Customizing the export job backoff strategy

By default, the export system will wait 1 minute, then 2 minutes, then 5 minutes, then 10 minutes thereafter before retrying a job. This is to prevent the server from being overloaded by a job that is failing repeatedly. That functionality is defined in the getJobBackoff() method on the exporter class:

/**
* @return int | array<int> | null
 */
public function getJobBackoff(): int | array | null
{
    return [60, 120, 300, 600];
}

You can read more about job backoff, including how to configure exponential backoffs, in the Laravel docs.

#Customizing the export job tags

By default, the export system will tag each job with the ID of the export. This is to allow you to easily find all jobs related to a certain export. That functionality is defined in the getJobTags() method on the exporter class:

public function getJobTags(): array
{
    return ["export{$this->export->getKey()}"];
}

If you’d like to customize the tags that are applied to jobs of a certain exporter, you may override this method in your exporter class.

#Customizing the export job batch name

By default, the export system doesn’t define any name for the job batches. If you’d like to customize the name that is applied to job batches of a certain exporter, you may override the getJobBatchName() method in your exporter class:

public function getJobBatchName(): ?string
{
    return 'product-export';
}

#Authorization

By default, only the user who started the export may download files that get generated. If you’d like to customize the authorization logic, you may create an ExportPolicy class, and register it in your AuthServiceProvider:

use App\Policies\ExportPolicy;
use Filament\Actions\Exports\Models\Export;

protected $policies = [
    Export::class => ExportPolicy::class,
];

The view() method of the policy will be used to authorize access to the downloads.

Please note that if you define a policy, the existing logic of ensuring only the user who started the export can access it will be removed. You will need to add that logic to your policy if you want to keep it:

use App\Models\User;
use Filament\Actions\Exports\Models\Export;

public function view(User $user, Export $export): bool
{
    return $export->user()->is($user);
}
