Being a copilot for Excel is an extremely challenging task. I've read many papers on this subject and feel that current technology is still far from achieving 90% or higher accuracy. If you frequently use ChatGPT to analyze Excel, I believe you also often encounter situations where it fails or makes mistakes, and this feature of ChatGPT (Code Interpreter) has been out for over two years now. Of course, ChatGPT is quite naive when handling Excel; it doesn't even bother to analyze how many tables are actually in a sheet, always foolishly treating each sheet as a single table.
