A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
This was my problem.
When I had auto calculation on, and I clicked "save", it kept on asking me
"Calculation is incomplete. Recalculate before saving?"
And I couldn't get past that no matter how many times I clicked.
I fixed it up by unticking auto calculation. And going to the recent sheets that I changed and on the "formulas" ribbon, clicked "calculate sheet". The "calculate" button did nothing, but "calculate sheet" fixed it.
Then turned back on the auto calculation and clicked save and it didn't ask me that any more.
