I switched to LibreOffice Calc. I program my sheets and don’t need all the bells and whistles of Excel.

If you’re using excel anyway, you’re probably not super worried about using non open source software. In which case, I find Google sheets to perfect. I use it for almost everything, because it’s just easier to use Google’s office suite for my school than it would be to use libre office, since everything backs up immediately across devices. I’ve never had any complaints about compatibility or format, and I’m literally being graded on my shit. I’d be preferable to use only open source software, from like a philosophical standpoint, but I also need things to function well in a world that expects automatic saving across devices and flawless compatibility to the arbitrary standard of Microsoft office
