I don't think tools like Claude are there yet, but I already trust GPT-5 Pro to be more diligent about catching bugs in software than me, even when I am trying to be very careful. I expect even just using these tools to help review existing Excel spreadsheets could lead to a significant boost in quality if software is any guide (and Excel spreadsheets seem even worse than software when it comes to errors).
That said, Claude is still quite behind GPT-5 in its ability to review code, and so I'm not sure how much to expect from Sonnet 4.5 in this new domain. OpenAI could probably do better.
