TOON to JSON converter

Going the other way matters just as much: when a model replies in TOON, or a teammate hands you a .toon file, this tool decodes it back to standard, pretty-printed JSON using the official reference decoder — so you also get validation for free. Malformed TOON produces a precise error instead of silently wrong data.

TOON is a lossless representation of the JSON data model, so decode(encode(x)) returns exactly x. Round-trip your data through both converters to prove it to yourself.
