How to use URL Query String Parser

Paste a query string beginning with ? or a complete HTTP(S) URL to decode parameter names and values.

?topic=tools&topic=calculators produces {"topic":["tools","calculators"]}.

What to know

Repeated keys become arrays, and + is decoded as a space. Input is parsed locally and never fetched.
