I’ve tried it and found it wanting at regex and excel formulas, but I’m glad to hear it’s working for you! Are you using 4? I haven’t tried that one and I hear it’s better.
I typically try 3.5 first and switch to 4 if the results aren't great. 3.5 typically handles basic use cases quite well, for example, writing regex that detects jira ticket naming nomenclature. For more complex things, I go to 4.
It sometimes gets things wrong, but I've also found that just saying "that didn't work" gets it to reevaluate for more complex situations
it helps if you hold ChatGPTs hand and walk it through what you need. For example if you have a regex with 3 requirements, ask it to write a regex for the first requirement, then ask it to modify the previous output to add another requirement, and so on. that way you can sort of "audit" it as it generates the correct regex.
there is some more discussion of this in a similar post from a few days ago.
