I\'ve got a collection of disparate, complex JSON objects from a CouchDB database. Each contains many levels of nested properties--for example,
tps_report.p
You can use my ObjectPath to query big nested JSON documents. The cause I'm building it is the lack of good tools in programming languages to work with JSON just as mentioned in the question.
The project is open sourced and under AGPL license.

Javascript implementation is not optimized and lacks half of the Python's functionality but I'm keen to add new things if needed by community - just ping me about what is crucial to you.
