I guess Claude maybe useful for finding errors in large Excel Workbooks. May also help beginners to learn the more complex Excel functions (which are still pretty easy). But if you are proficient at building Excel models I don't see any benefit. Excel already has a superb very efficient UI for entering formulas, ranges, tables, data sources etc I'm sceptical that a different UI especially a text based one can improve on this.
I understand the sentiment about a skilled user not needing this, but I think having a little buddy that I can use to offload some menial tasks would be helpful for me to iterate through my models more efficiently; even if the AI is not perfect. As a highly skilled excel user, I admit the software has terrible ergonomics. It would be a productivity boon for me if an AI can help me stay focused on model design vs model implementation.
For some reason, I find that these tools are TERRIBLE at helping someone learn. I suspect because turning one on, results in turning the problem solving part of ones brain off.
Its obviously not the same experience for everyone. ( If you are one of those energized while working in a chat window, you might be in a minority - given what we see from the ongoing massacre of brains in education. )
Paraphrasing something I read here "people don't use ChatGPT to do learn more, they use it to study less".
Maybe some folk would be better off.
