// Change the export file format into .xls
add_filter( 'wpcie_export_file_format', function(){
return "xls";
} );
File format that is accepted to change are:
- xls
- xlt
- xla

To add additional file format in the accepted list, check the sample code on how to.
// Copy and paste this code in your theme function.php file.
// Adding xltx file format in the list
function my_additional_format_list( $format_list ){
$format_list[] = 'xltx';
return $format_list;
}
add_filter( 'wpcie_export_file_format_list', 'my_additional_format_list' );
