That’s a Microsoft app. Check for Office updates and test again,

Failing that, exit all Microsoft apps, and clear the Microsoft cache, and try again,

[Finder app, use Go to Folder in the menus to go to ~/library/caches, and delete the com.microsoft.Excel folder.]

Failing that, remove and re-install Office and test again,

Failing that, contact Microsoft support.

Failing that, load LibreOffice or the Apple Numbers app or some alternative spreadsheet app, and use that.
