Python:JSON

import json

Enable json functions. The json module is standard available (no installation needed)

Read a json file and return it as dict.

import json
with open(filename) as fh:
    data = json.load(fh)

json.dumps(dict, indent=4)

Convert a dict into a json string nicely structured. Indent each level with 4 spaces.

Can be used on other datatypes too.
