How to Validate Multiple Sheets In Laravel Excel?

To validate multiple sheets in Laravel Excel, you can use the SheetsValidation interface provided by Laravel Excel. This interface allows you to define validation rules for each sheet in your Excel file.

To implement sheets validation, you can create a custom validation class that implements the SheetsValidation interface. Within this class, you can define the validation rules for each sheet by using Laravel's validation methods.

Once you have created the custom validation class, you can apply it to your Excel import or export process by passing an instance of the class as a parameter to the withValidation method in your import or export job.

By following this approach, you can easily validate multiple sheets in your Excel files using Laravel Excel.

1. Create a new Laravel project or navigate to an existing Laravel project.
2. Install the Laravel Excel package by running the following command: composer require maatwebsite/excel
3. Publish the configuration file by running the following command: php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider"
4. Create a new Excel export class by running the following command: php artisan make:export MultiSheetValidationExport
5. In the newly created MultiSheetValidationExport class, implement the WithMultipleSheets interface and define the sheets method to return an array of sheet classes. For example: use Maatwebsite\Excel\Concerns\WithMultipleSheets; class MultiSheetValidationExport implements WithMultipleSheets { public function sheets(): array { return [ 'Sheet1' => new Sheet1Export(), 'Sheet2' => new Sheet2Export(), ]; } }
6. Create the Sheet1Export and Sheet2Export classes by running the following command: php artisan make:export Sheet1Export php artisan make:export Sheet2Export
7. Implement the necessary export logic in each of the Sheet1Export and Sheet2Export classes.
8. Define validation rules for each sheet in the rules method of the Sheet1Export and Sheet2Export classes. For example: public function rules(): array { return [ 'name' => 'required|string', 'email' => 'required|email', // Define more validation rules here ]; }
9. Use the Laravel Excel facade to export the data with validation. For example: $export = new MultiSheetValidationExport(); return Excel::download($export, 'multi-sheet-validation.xlsx');

By following these steps, you can implement multi-sheet validation in Laravel Excel by defining the validation rules for each sheet in their respective export classes and returning an array of sheet classes in the main export class.
