How it works

Paste a full URL or just the part after ?. Each key=value pair is percent-decoded (+ becomes a space). Repeated keys become arrays, and with nested keys enabled, PHP/Rails-style brackets build nested objects.

FAQ

Does it handle application/x-www-form-urlencoded?

Yes — form bodies use the same format as query strings.
