Auto-generate plain old object models + custom JSON serialization/deserialization code from JSON schema definitions.
Js2model makes it easy to use JSON data as plain old Objective C, C++, or Python objects.
Js2model addresses the aforementioned shortcomings of typical JSON deserialization approaches by automatically generating model classes and serialization/deserialization code. Js2model uses the JSON Schema definition of your JSON data to generate source files which you include and build with the rest of your project.
The script is designed to target multiple output languages. Objective-C and C++ are supported out of the box. Future versions will add additional languages, as well as support for adding your own language templates.

Chances are you do not have existing JSON Schema definitions for your JSON data. Theoretically, creating a schema is simply a matter of creating JSON file per the JSON Schema specifications. Realistically, creating a schema definition manually can be tedious and time intensive, depending on the complexity of your data. Luckily, there is a better way. GenSON is a script that will automatically generate JSON Schema from one or more JSON files. The resulting schema definitions may need some tweaking, but GenSON will save you considerable time and effort.
