How to create a views export in XLS format? I have a view that extracts user informations. Now I need to export these results in XLS format. I have tried "views data export", but it is not supported in last Excel versions.

Is there some way that permits me to export data in XLS for the new Excel versions ? Or a good library to use via a custom module ? I'm a senior developer so I have no problem to use PHP and other features.
The Views Data Export PHPExcel should suffice:


  This module extends Views Data Export module to allow XLSX files export.


That format is supported by Office 2007 and up.

Or go with what Brady said in comments and use CSV, it should be just as good.
