Microsoft excel/word files will not open in Catilina
Anyone else having issues with MS file formats for Excel/Word no longer opening in Numbers/Pages after upgrading to Catilina? Prior to upgrading I could open all my historical (and I have 1000's) Excel/Word files no problem, now I get an error message ....The document "filename/xlsx" could not be opened"..... I called Apple support and the tech was not helpful, basically said they have ben getting some calls, that he really has no explanation why and my options are to call MS support and see if they have a way to convert or subscribe to MS 365. I don't want to pay for a subscription service I use sparingly and would prefer to use my Apple apps going forward. Any suggestion from wiser folks than me out there would be appreciated.
