How to Download an Excel File In Laravel?

To download an Excel file in Laravel, you can create a route that points to a controller method which generates and returns the Excel file. Within the controller method, you can use the response() helper function to send the Excel file as a download to the user. Make sure to set the correct headers to specify the file type and name. You can use a library like Maatwebsite's Laravel Excel to easily generate Excel files in Laravel. Once you have your Excel file ready, you can use the download() method to send the file as a download response.

What is the impact of Laravel routing on Excel file downloads?

Laravel routing does not have a direct impact on Excel file downloads. Excel file downloads can be implemented in Laravel by creating a route that triggers a controller method to generate and return the Excel file. The routing in Laravel simply defines how the request is directed to the appropriate controller method for handling the Excel file download. It is the controller logic that actually handles the file generation and response.

}

Route::get('/download-excel', 'YourControllerName@downloadExcelFromS3');
