Excel “Trace Dependents” stops working in XLSX files generated by ChatGPT

That may have been the case in your specific environment, but it cannot be taken as a general statement.

I had a test file created; here is the chat: 

https://chatgpt.com/share/6adb6f75-8e64-83ed-bf25-ffeb12fec7c2

As you can see, this file works without any issues, and the attribute you mentioned is not present in the file. However, if you deliberately force the scenario you described, then that behavior can indeed be observed.

Therefore, the same rule applies here as with everything involving AI: an AI can make mistakes, so you must verify the results yourself.

If you create the file yourself using Excel and then compare the XML code, you will find that Excel itself saves far more code than what ChatGPT generates. Generated Excel files should always be used with caution, regardless of which program created them.
