Alternatives

• If you are not using class-based Python models and have no restrictions on the structure of the JSON representation:
  • Python's in-built json library will work out the box with its default encoder (JSONEncode) and decoder (JSONDecode).
  • demjson can encode and decode JSON with added syntax checking.
  • ultrajson is claimed as an "ultra fast" JSON encoder and decoder.
  • py-yajl is yet another "fast" JSON encoder/decoder.
• If you are using class-based Python models but your JSON need not be human readable and you are not concerned with interoperability:
  • jsonpickle will automatically serialize objects.
  • py-importjson.
• If you want to deserialize flat data files into Python dict objects using mapping schema:
  • jsonmapping
• If you do not mind coupling your Python models to the serialization library:
  • jsonobject.
• If you only wish to serialize models using a mapping schema and are not interested in deserialization or compatibility with Python's in-built json library.
  • serpy can serialize complex models with arbitrary mappings from fields and methods to JSON.
