A software question [View all]

I am going to work on some dbs for the local Democratic Party org. I have Libre on my laptop. I checked and found information that I can work in Libre document and save a spreadsheet as an Excel document. I did a test and saved a Libre document as an Excel. It opened as Excel (unlicensed product) I'll be working with an Excel sheet that I'd open in Libre and save as Excel, and then return to the Dem office when I complete the work I'm doing.

Should I do that, or just download an Excel trial? I don't want to mess up the local dbs that I'll be working with. I'm retired, so I don't really need more than what I have for my own work.

Thanks for any insight. I sure liked it better when the software came with the hardware.
