We use sheets all the time at work for all sorts of processes, essentially an internal tool. But it doesn't really even need code, the human is the code. I had to strongly suggest to some of our TPMs and actually a principal in the last year that no they didn't need a tool, they just needed a spreadsheet. But this is so low code that people likely don't even think of it as a low code solution, it's just a spreadsheet.

That said other than managing and sorting lists of work to do, I break the limits on sheets and excel all the time so for anything with customer scale data I can't use it.
