Heya, sorry I have not responded to this thread in a while. Been a full time dad for a few weeks and so have only had late evenings to work.
I have not yet tried to directly parse json in the app itself but am using tokenat and using my flask backend to do the hard parsing work for now. Fortunately the api I am using is not very involved.
I am interested in how the CSV plugin can be used to parse json though as that could indeed be very helpful. I will keep you guys informed.
I have also been playing with the idea of using the calljs plugin to call some custom js that deals with specific bits of json.
