Excel for Mac does not support multiple cores and has a much more limited set of hotkeys, along with a more limited universe of addons.

this. I think most office workers couldn't care less if they run Windows. But they know those Excel hotkeys as well as any Vim hacker knows the escape key.

As a vim to excel user I’ve always wanted to create an addon that maps vim hotkeys to excel. My only fear is that I’d get too used to it and not be able to use any machine that I sit down at.

Those products in Wine. Google web, office 365, libre/open office, atom/sublime, vim/emacs.

LibreOffice.

LibreOffice has come a long way, but retraining thousands of employees is impractical.

That is as they say "a brave choice"

My job switched completely to GSuite a year ago, management first.

If anyone needs Excel they get it.

So far I've spotted I one person that probably uses Excel. No complaints that I've heard or seen.

Ah so how do you handle working with external people who use excel.

Most of my work with a wildly spread organisations and we can have excel go through US to Russia to Uk Back to Ukraine and then back to me in the UK
