Aside from macros, keyboard shortcuts, and .xlsx files, why else would someone be compelled to stick with Excel? Seems like the rest of the tabular data stuff could be done in Google Sheets or some other product and yield the same results.
People are wedded to Excel because they've spent a lot of time learning it and don't want their skills to become obsolete. The resistance is rooted in psychological / political reasons, not technical ones.
Or is your aversion mostly to the M- word?
I find it funny that when it comes to vi vs emacs (or any such similarly geek-approved thing), fans of each will jump up in arms about the precise reason their platform is better, but the same kind of people would not want to take hundreds of thousands of business professionals at their word about why they like using a particular piece of software.
