I Love FOSS but trust me, you can’t compare MS Excel to Libre Calc, it’s far far ahead. Even the web version which is worse than the actual Excel version is better than Libre Calc. Libre Calc can’t hold a candle to Microsoft Sheets when it comes to features.
I really can’t think of anything that excel can do that libre can’t in a business setting. Libre office has a lot of functionality. I haven’t touched Ms office in two years now.
it’s more about cross compatibility for me and there are many things I think. It lacks many of the advanced features that Excel has. But still, even if it did have it, I have to collaborate and I just can’t take chances of in compatibility (one of the reasons I am edit:not even going to use OnlyOffice which has greater compatibility. )
