I also love gron, if nothing else to find the paths I need to use with jq later.

But ChatGPT has genuinely solved my suffering writing jq, it does a pretty good job. It even almost replaces gron, if you feed it an exmaple json and ask for jq, it gives you something. It usually needs a little adjusting but it gets me 90% of the way there and saves me a bit of time.

I rarely use it for much else but its a jq winner :)
