The issue is that the average Excel user doesn’t quite have the skills to validate and double-check the Excel formulas that Claude would produce, and to correct them if needed. It would be similar to a non-programmer vibe-coding an app. And that’s really not what you want to happen for professionally used Excel sheets.
IMO that is exactly what people want. At my work everyone uses LLMs constantly and the trade off of not perfect information is known. People double check it, etc, but the information search is so much faster even if it finds the right confluence but misquotes it, it still sends me the link.
For easy spreadsheet stuff (which 80% of average white collars workers are doing when using excel) I’d imagine the same approach. Try to do what I want, and even if you’re half wrong the good 50% is still worth it and a better starting point.
Vibe coding an app is like vibe coding a “model in excel”. Sure you could try, but most people just need to vibe code a pivot table
