About Query String Parser
Inspect a complete URL or decode query parameters into structured JSON. Repeated parameter names become arrays, and builder mode turns a flat JSON object back into a correctly percent-encoded query string.
How to use
- Choose parse or build mode.
- Enter a URL, query string, or JSON object.
- Copy the structured or encoded result.
FAQ
How are repeated query parameters handled?
Parsing stores repeated values in an array. Building an array writes the same parameter name more than once, preserving the common query-string convention.
