The less nice thing, though, is that the model of the process you're starting from -- the actual spreadsheet -- has, as you say, these structural problems. And since (some speculation here, but I very much suspect that) many different processes, after having been so mangled, will end up in the same redundant, excessively-flattened structure, you can't determine from the spreadsheet alone which of these different processes it is supposed to encapsulate.

So before you can start "shifting this structure around" you'll still have to go through a standard business analysis process to find out what you are going to shift it into. And if you're already doing that... Well, then most of your promise of automation is out the window already, so what's the use of having the actual implementation done in some weird newfangled "no-code" or "low-code" tool?
