I’ve been dual-booting Linux and Windows for a while, with Windows as the fall-back option in case I wanted to use Office for something. Now that they tried to trick me into paying a subscription for their AI slop machine, I’m finally, fully out. It was a pain to actually track down and back-up the stuff that was held for ransom in OneDrive, but now it is done.
LibreOffice is good alternative if you are not heavily dependant on unique MS Office features, especially Excel.
OnlyOffice is better if you’re looking for MS Office document compability.
