Question :
I am running the latest version of MS Excel, but even though it should include the XLOOKUP function, it is not appearing when I want to use it in a formula.

What can I do to fix this ?


Answer :
The problem is that even though you have the latest version of MS Excel installed, the active license you have is one for MS Excel 2019 or earlier…
So, make sure you have a license for a newer version of MS Office for Mac, then do this :
– in Excel, click on “Excel” in the top menu bar
– from the pulldown menu, select “About Microsoft Excel”
– in the “About Excel” window that opens, at “License:” you will see “Office … 2019” (or something alike)
– now, go to the Microsoft website and download the License Removal Tool for Mac
– when downloaded, run the .pkg file and follow the online instructions
– when done, move the downloaded .pkg file to the trash
– then, open any MS Office app (e.g. Excel, Word, PowerPoint or Outlook)
– when prompted, typ your MS Office for Mac license code (for Office 365 or 2021 or newer)
– when done, restart your Mac to activate the license code
– then open Excel after startup and check : XLOOKUP will now be available under “Formulas” > “Lookup & Reference”

That’s it !
enjoy 😉
