Have only recently started using JQ, and it's absolutely brilliant. I'm on wsl2/Ubuntu - just pipe any Json content to it, and you get an easy to read colour version rather than your regular monotone output (which seems incompatible with my brain).
And you can then create queries to select certain keys - highly useful if you're dealing with monster documents, and customise the output of that (eg to reduce into just the info you need). Plus probably much more, but those are the features I've used so far. Big thanks to the Devs!
jq is great! Just so you know, there are similar programs for many other languages, like yq [0]. Also, there are interactive `jq` prompts like `ijq` [1].
