When I close a spreadsheet, I get a message that says, "Microsoft Office
Excel recalculates formulas when opening files last saved by an earlier

to turn off automatic calculation, but I handle dozens of spreadsheets every
day, and I get tired of clicking "no" every time I close a spreadsheet.
Thanks in advance!

Not used this in a while, but I believe if you click yes, and allow
Excel to save the file, it will save in the latest format, so you will
not see this issue again for that file. (ie you have to deal with the
problem once for each file).

Alternatively, a registry edit (major caveat, registry hacks come with
a health warning) should solve the problem.
