How to use Libre office with third party applications

Libre calc is not working with third party applications which can export data to excel. Data can be easily exported while using WPS office or MS office. How to rectify this?

It is not clear from your question whether you want to export from LO or whether you wish to import data from a third party application. In either case, what file format?

Most probably, you post to a wrong place. Contact the vendors of those applications and request support for LibreOffice file format.
