URL Query Parser Online
Parse URL query parameters locally, inspect decoded keys and values, review repeated parameters, and copy grouped JSON output for debugging or campaign QA.
A URL query parser extracts the part after the question mark and displays each parameter clearly.
It is useful for debugging links, UTM tags, filters, redirects, and app state URLs.
Full URLs
Paste landing page links, redirect URLs, analytics links, or app URLs.
Raw query strings
Paste only the query string when you do not need host or path context.
Each key-value pair is shown in order, and repeated keys are preserved in the table.
The JSON output groups repeated keys into arrays so they are easier to copy into notes, tests, or bug reports.
Use this with UTM Builder when you need to inspect campaign links after copying, shortening, or redirecting them.
For editing encoded values directly, use URL Encoder and Decoder.
UTM checks
Confirm utm_source, utm_medium, campaign, term, and content values before launch.
Bug reports
Extract filter, sort, and app state parameters from a reproduced URL.
Redirect QA
Check whether query parameters survived a redirect or copied link.
Developer notes
Convert a query string into grouped JSON for docs, tests, or handoff.
Example
A campaign URL with utm_source and plan parameters becomes a readable table plus grouped JSON.
Assumption
The input is a valid URL, path with query, or query string using standard encoding.
Limitation
This tool parses query parameters only. It does not fetch links, follow redirects, or validate analytics configuration.
Does this tool open or fetch the URL?
No. It parses the text locally and does not request the URL.
Can it parse repeated keys?
Yes. Repeated keys appear as separate rows and as arrays in copied JSON.
Can it parse UTM parameters?
Yes. UTM parameters are standard query parameters.
Can it decode percent-encoded text?
Yes. Browser URL parsing decodes standard query parameter values.
Suggested workflow
URL debugging path
Create or paste a link, parse query values, and encode or repair parameters before sharing.
