+Actions can return anything but are not required to. This makes it very simple to redirect the user to another page or to download an [export](/usage/exports) of the records.
+
 When an action has been executed, it will automatically clear the selection and refresh the table. This can be prevented
 if you return `false` from your callback.

+# Exports
+
+Exporting data from the table can be really useful to quickly get all records in a spreadsheet. Creating an export functionality is very simple using [actions](/usage/actions).
+
+The example below makes use of [maatwebsite/excel](https://laravel-excel.com/). It is not required to use this package, as you can use anything you want. If you are planning to use `maatwebsite/excel`, please follow the installation instructions before continuing.
+
+## Example
+
+Start by adding an action to your table. This example will make use of a [standalone](/usage/actions#standalone) action. By doing so, all records that are available in the table will be included in the export while respecting all filters and sortings.
+
+```php
+protected function actions(): array
+{
+    return [
+        Action::make(__('Export All'), 'export_all', function (): mixed {
+            $collection = $this->appliedQuery()->get();
+
+            return Excel::download(
+                new BlogExport($collection), 'blogs.xlsx',
+            );
+        })->standalone(),
+    ];
+}
+```
+
+You can also use a regular action, only exporting records that have been selected.
+
+```php
+protected function actions(): array
+{
+    return [
+        Action::make(__('Export'), 'export', function (Enumerable $models): mixed {
+            return Excel::download(
+                new BlogExport($models), 'blogs.xlsx',
+            );
+        }),
+    ];
+}
+```
+
+An example of the `BlogExport` could look like the following. Note that any formatting can be applied in this class.
+
+```php
+<?php
+
+namespace App\Exports;
+
+use Illuminate\Support\Collection;
+use Maatwebsite\Excel\Concerns\FromCollection;
+
+class BlogExport implements FromCollection
+{
+    public function __construct(
+        protected Collection $collection
+    ) {
+    }
+
+    public function collection()
+    {
+        return $this->collection;
+    }
+}
+```
