Surprised you would think that JSON is more human-readable, as the layout of that makes it visually quite appalling - not so bad when through a pretty-printer utility, admittedly, but may as well go for XML as another use case

For ages I would just dump json files in a browser and let it auto-pretty print it for a first look.

A while back I discovered https://dadroit.com/ which is small (in feature set) but perfectly formed (nicely designed and extremely fast, even on huge files).
