How to beautify JSON in Python?

Question

Can someone suggest how I can beautify JSON in Python or through the command line?

The only online based JSON beautifier which could do it was: http://jsonviewer.stack.h

Answer 1

It looks like jsbeautifier open sourced their tools and packaged them as Python and JS libs, and as CLI tools. It doesn't look like they call out to a web service, but I didn't check too closely. See the github repo with install instructions.

From their docs for Python CLI and library usage:

To beautify using python:

$ pip install jsbeautifier
$ js-beautify file.js

Beautified output goes to stdout.

To use jsbeautifier as a library is simple:

import jsbeautifier
res = jsbeautifier.beautify('your javascript string')
res = jsbeautifier.beautify_file('some_file.js')

...or, to specify some options:

opts = jsbeautifier.default_options()
opts.indent_size = 2
res = jsbeautifier.beautify('some javascript', opts)

If you want to pass a string instead of a filename, and you are using bash, then you can use process substitution like so:

$ js-beautify <(echo '{"some": "json"}')
