I would like to install excel, word and powerpoint without windows, because carrying my giant laptop to uni is less practical than the tiny steam deck and a small keyboard. Is there any proton magic that allows me to install the programs? I don’t care about one drive and online features.
Yes libre office works really well. I prefer it over ms office. Less bells and whistles.
And you can still save in the (not latest) Ms format for compatibility.
I was about to suggest it myself. LibreOffice kicks ass.
