Parse URL Query Parameters for Free

Paste a complete URL or its query string and parse the parameters into readable output. Inspect each decoded name and value, checking repeated names carefully because only their final value remains in the result.

Convert a Query String to JSON for Free

Supply query text to produce a JSON object suitable for reviewing parameter values. Compare it with the source before copying; duplicate parameter names collapse into one key carrying the last supplied value.

Decode URL Parameter Values for Free

Enter the URL containing encoded query values and inspect the parser's decoded names and contents. Check spaces, punctuation and repeated keys against the original string before using the JSON output in a debugging note.
