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. )
