standardjson

JSON encoder fully compliant with the ECMA-262 and ECMA-404 specifications.

• Free software: BSD license
• Documentation: http://standardjson.readthedocs.org.

Features

Support for all objects that the Python stdlib’s json.JSONEncoder can encode, plus:

• datetime.datetime
• datetime.date
• datetime.time
• decimal.Decimal

Works on Python 2.6, 2.7, 3.3. Probably works on 3.4 and 3.5 but I haven’t set up tests for those with Tox yet.

Quickstart

Use StandardJSONEncoder as you would use json.JSONEncoder from the Python standard library:

>>> import datetime
>>> import json
>>> from standardjson import StandardJSONEncoder

>>> json.dumps({'day': datetime.date(2010, 2, 17)}, cls=StandardJSONEncoder)
'{"day": "2010-02-17"}'
