I wrote a json parser which creates a Tcl list which can be converted
back to a json structure:

http://junom.com/json/

Code is in the .tcl~ files, or you can try out the conversion with the
web form.

The code has no helper functions to look up data, or anything to
create a json structure, but it does create a Tcl encoding which
distinguishes the different structural elements to any depth.

The main difference between json and tcl structures is that both
arrays and lists are anonymous in json, not sure if a dict actually
matches up with a json structure.
