How to customize the Excel export file name
When exporting your DataTables View to an Excel file, the default file name combines the View name and your website name.
Add your preferred file name on line 3 between the single quotes:
add_filter( 'gravityview/datatables/button_excel','gravityview_excel_export_settings', 10 ,2 );
function gravityview_excel_export_settings( $button_config = array(), $view_id ) {
$button_config['filename'] = 'YOUR-NEW-FILENAME-HERE';
$button_config['title'] = '';
return $button_config;
}
