json-flatten

Python functions for flattening a JSON object to a single dictionary of pairs, and unflattening that dictionary back to a JSON object.

Useful if you need to represent a JSON object using a regular HTML form or transmit it as a set of query string parameters.

For example:

>>> import json_flatten
>>> json_flatten.flatten({"foo": {"bar": [1, True, None]}})
{'foo.bar.[0]$int': '1', 'foo.bar.[1]$bool': 'True', 'foo.bar.[2]$none': 'None'}
>>> json_flatten.unflatten(_)
{'foo': {'bar': [1, True, None]}}

The top-level object passed to flatten() must be a dictionary.
