Query String Parser
Parse query strings, full URLs, repeated parameters, and pasted parsequery-style snippets into readable JSON and copyable key/value rows in your browser.

Query parser examples
Quick answer: paste a full URL or the part after ? to turn query parameters into decoded rows and JSON. The parser handles repeated keys such as page=1&page=2 as grouped values so API, analytics, and redirect debugging notes are easier to read.
Use this page when you need to parse query string values from campaign links, redirect URLs, API request logs, or a pasted parsequery note from a ticket. It accepts both full URLs and raw strings like ?utm_source=google&page=1&page=2.
Parse query string data
Paste a query string to decode percent-encoded values, spot missing parameters, and group repeated keys before sharing a clean JSON view.
Decode encoded values
Use URL Encoder/Decoder first when a parameter value is still percent-encoded, then return here to inspect the parsed table.
Move from URL parsing
Use URL Parser first when you need protocol, host, path, hash, and query parts together, then use this tool for a focused parameter table.
Format the result
Send parsed JSON to JSON Formatter or compare structured exports with CSV Formatter when documenting API or analytics issues.
When this parser helps most
Use it before filing a developer ticket, checking UTM tags, comparing duplicate parameters, or copying a readable parameter table into QA notes. It does not visit the pasted URL, follow redirects, validate analytics setup, or decide whether a token is safe to share.
Token and privacy caution
Query strings can contain email addresses, session IDs, signed URLs, invite codes, private filters, or access tokens. Redact sensitive values before sharing parsed output in a ticket, prompt, screenshot, or public issue.
Quick answer
Query String Parser is a browser-based query string parser for checking copied developer data such as payloads, URLs, encoded values, identifiers, snippets, or logs without sending the input to a server.

What this tool does
This URL query parameters parser extracts parameters after the question mark, decodes percent-encoded values, groups repeated keys, and prints both JSON and tabular output for debugging links, campaigns, redirects, API requests, and parse query handoffs.
Common use cases
Parse query string parameters, inspect repeated keys, decode campaign or API request data, and turn parse query handoffs into readable output.
Use Query String Parser when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste a full URL, a raw query string, or parameters copied after a question mark into the input box.
- Review decoded JSON, repeated-key arrays, and key/value rows in the output panel.
- Copy the parsed query output for docs, debugging, QA notes, or developer tickets.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Client-side only: the URL or query string is parsed in your browser and is not uploaded, stored, fetched, or logged.
Practical notes for this tool
Best use case
Use Query String Parser when a copied URL, tracking link, API request, or redirect needs its URL query parameters separated into readable rows before debugging duplicate keys, campaign tags, parsequery notes, or support tickets.
Inspect campaign parameters and repeated keys
https://example.com/search?utm_source=newsletter&q=blue%20widgets&page=1&page=2
utm_source = newsletter q = blue widgets page = 1 page = 2 JSON groups repeated page values as an array.
Privacy and local processing
Query parsing runs locally from the URL or query string you paste. ClearUtils does not fetch the URL, click the link, upload parameters, or store campaign data.
Limitations to know
- It does not follow redirects or inspect server logs.
- Duplicate parameters may depend on how the receiving app interprets them.
- It does not validate whether UTM, API, or tracking parameters are correct in the destination system.
- Remove private tokens, session IDs, and customer identifiers before pasting URLs.
Practical FAQ
Does parsing a query string check whether tracking is configured correctly?
No. It makes parameters readable so you can spot missing, duplicated, or oddly encoded values. Analytics setup and redirect behavior still need to be verified in the destination system.

5 focused answers for this page
Can this parse a full URL?
Yes. Paste a full URL or only the query string and the tool extracts the parameters after the question mark.
Can I use it to parse query string values from a ticket or log?
Yes. Paste a raw query string such as ?utm_source=google&page=1 or a parsequery-style note copied from a ticket, and the tool decodes values into JSON and rows.
Does it handle repeated query keys?
Yes. Repeated keys are grouped as arrays in the JSON output and listed individually in the table output.
When should I use URL Parser instead?
Use URL Parser when you need protocol, host, path, query, and hash together. Use Query String Parser when the main job is to parse query parameters.
Is query data uploaded?
No. Parsing runs locally in your browser and ClearUtils does not upload, store, fetch, or log the pasted URL or query string.
