Unless you have syntax-aware grep support, I don't see how searching nested key json could be better. But grep is the default installed. Not to mention ad-hoc languages that does not have any IDE support.
`gron` is so underrated. Usually when I try to show people who useful it is they don't seem to understand how powerful it is. One common use is showing how to customize only one part of a helm chart by checking values of an already installed chart:
That snip could be provided to another team or a customer as a yaml file that could be included with `helm upgrade -f whatever.yaml`. This is soooo much easier than digging that limited set of data out of the much more detailed data.
