I changed the dnd_extra_mime_types function as follows:

function dnd_extra_mime_types( $mime_types ){
		$mime_types['xls'] = 'application/excel, application/vnd.ms-excel, application/x-excel, application/x-msexcel';
		$mime_types['xlsx'] = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet';
		$mime_types['RPP'] = 'Reaper_files';
		return $mime_types;
	}

but still doesn’t work. What else has to be changed?

Thanks, that worked!
