Its all about Excel. It really is the best spreadsheet, and everyone knows how to use it. But that comes in an Office bundle that includes Teams. And that is why we must suffer.
I agree with it, but it's a wild world we live in when the best spreadsheet has default behaviors which will fuck your data pasted into it when you're not paying attention.
Was certainly the case in the early years of Google Sheets. For me, the gap is entirely closed. I'm willing to believe that Excel still has the better platform for extreme power users but I've done some pretty slick stuff with Google Sheets and that was four or five years ago. It must be even better today (though I'm not currenlty doing much with spreadsheets).
