Depends on the profession. The company might shell out money for accounting to use excel. But PMs, engineers, TPMs, etc etc are likely to be told “hey we’re using google workplaces and aren’t going to buy you an excel license” unless you can make a very convincing case. That represents a shrinking pie for Excel even if specific professional use remains on Excel while everyone else moves on. Similar stuff happened with things like COBOL, IBM mainframes, etc. That’s why Microsoft competes with their 365 offering, but Google really put a dent in Microsoft’s near monopoly on OS+productivity tools that they built up and cemented in the 90s/early 00’s.
