Released: JSON Library
Ground up build of a JSON all-in-one library. Read it, modify it, write it. Heavily commented, completely configurable in scale.
Releasing this to help anyone out that needs to get as close to full JSON integration as possible, and also in hopes that people will contribute to it to make a better library for everybody. Feel free to use, update, suggest changes, etc. If you have any problems with it, please let me know. I've been using it for a while now and it's been pretty solid. Testing on an NI-3100 and it's a pretty low CPU hit.
Running JSON_ParseObject on a JSON string will validate it first, then parse it into a _JSON_Object structure variable. The structure has an array of Key:Value pairs that also give you the type of value (string, number, array, etc). JSON_ObjectToString takes a _JSON_Object and returns it as a string for writing to files or whatever. And there's a load of other supporting functions in there for setting values, deleting keys, and what not.
