How come i cannot download my Numbers file to my desktop or convert it to Excel?

Hi, problemguy.

Thank you for visiting Apple Support Communities.

I understand that you are unable to access iCloud Drive documents. Could you provide more information on what exact issues you are experiencing? I would also need to know what Mac OS X version you are using to provide a better answer. However, here is a troubleshooting article that may help with this scenario.
