> I helped one recently almost one-shot[3] converting a 30 sheet mind numbingly complicated Excel financial model to Python with Claude Code.
I'm sure Claude Code will happily one-shot that conversion. It's also virtually guaranteed to have messed up vital parts of the original logic in the process.

I doubt that 30-sheet Excel model itself was validated by the most rigorous of standards. Unless it had its own test suite before the one-shot (which could be leveraged by the AI), people have probably been taking its outputs for granted for years.
