Emacs mode to edit JSON

Question

Does anybody know a good Emacs mode to edit JSON? An app I am working on uses a JSON based communication protocol and having the data nicely indented and syntax-highlighted woul

Answer 1

json.el by Edward O'Connor is part of GNU Emacs since 23.1 (2008).

While it isn't a syntax highlighter, it has a useful function to format JSON:

M-x json-pretty-print-buffer RET

So, if you have a recent version of Emacs, there is no need for jq or python -m json.tool.
