I wouldn't hold your breath waiting for my solution, it's currently a
constructive procrastination project to see if it is possible ;)

I made this:

https://github.com/jkitchin/jmax/blob/prelude/ox-json.el

which does give some output that vaguely resembles json for a very simple
org-file (no quotes, no effort to make compliant json, or pretty print it,
for example). This handles headlines, italic, bold text, links, paragraphs,
and plain text.

I don't have much need for this right now, so it will probably not advance
much, but you might find it a starting point for you if the parse-tree
doesn't pan out.
