Excuse me, I have some problems using .xls files on LibreOffice Calc. I tried opening the file and it worked but when I tried to save my work, it crashed. Is there any way to make it work?
It worked on Microsoft Excel on Windows 11. The file crashed the computer, but it worked passed 5 minutes and I could save my work.
Dang! How does it take to open that file? Are there formulas and macros in there?
As the others said, a spreadsheet isn’t a database. And you now experience why. Tell your boss it’s not going to work anymore.
