Fetch JSON from a URL and flatten it into discrete, greppable assignments — a browser-based take on tomnomnom/gron.

Ready.

Give it a URL that returns JSON. Every value becomes one line you can grep, diff, or paste into a bug report:

json.owner.login = "tomnomnom";

Browsers block cross-origin reads unless the server sends CORS headers. If a fetch fails for that reason, tick Route through CORS proxy to relay the request through allorigins.win — a third-party service, so don't send it anything private.
