Ok yep, fair. My comment was about using copilot-ish tech to generate plausible looking spreadsheets.

The kind of things that a domain expert Brenda knows that ChatGPT doesn't know (yet) are like:

There are 3 vendors a, b, c who all look similar on paper but vendor c always tacks on weird extra charges that take a lot of angry phone calls to sort out.

By volume or weight it looks like you could get 100 boxes per truck but for industry specific reasons only 80 can legally be loaded.

Hyper specific details about real estate compliance in neighbouring areas that mean buildings that look similar on paper are in fact very different.

A good Brenda can understand the world around her as it actually is, she is a player in it and knows the "real" rules rather than operating from general understanding and what people have bothered to write down.
