Hi robo2084,
I apologize for all the trouble it has caused and sorry about your time.
As per your description, the Import XML file to Excel feature is now available on Excel for Mac version 16.43, you can go Data>From Text and then choose the XML file. You could go Excel>About Excel to check the version.
Additionally, here are some sources I found for your reference:
EXCEL For Mac needs a XML import data

I appreciate your patience and understanding.
Best Regards
