So I have to upload files to enable syntax highlighting. There is probably a reason but the users frustration is helping them to look for alternatives.
I think main problem people trying to solve is treating JSON as computer-human interface. It was not designed for it and I don’t think we need to expand its use-case. You can perfectly use subset of YAML with much better readability for human interactions. I wrote custom parsers for subset I need with like 100 lines of Python code. JSON should stay as a loggable system-to-system format that you can render in a more readable way.
