Out of experience Majority of people don’t get even basic functionality of excel. Including IT professionals. If they can do complex functions without programming. They will learn to code out of a need to speed up their work.
One of my themes in class is that the bar is actually pretty low for becoming the local Excel "expert" is pretty low at most companies. I.e., just knowing how to write formulas with both relative and absolute references is a superpower. Today we added tables and names for cells/rages. Later will call some APIs and add some SQL. This is for business majors, not CS students, so really advanced stuff in context.
