But parent is still correct on "zero percent understandability".

I have seen dozens upon dozens of Excel sheets which "just worked" until they didn't and then of course person who could fix that left company 10 years ago.

Besides I also know dozens of people whose life would be easier if they would learn a bit more of Excel like pivot table is there for them.

For some quantity of use. When I say infinite customizeability I mean its just fronting chat gpt + tools without any real product use case.
