URL Query Formatter
URL Query Formatter online tool for parsing full URLs or query strings locally, decoding values, counting repeated parameters, and copying clean output.
About this tool
URL Query Formatter turns a full URL, a leading-question-mark query, or a raw query string into a readable table and structured JSON.
It preserves repeated parameters, shows raw and decoded values, and can emit a compact query string for API debugging, tracking checks, and redirect review.
Best use cases
- Clean up API URLs with many GET parameters and verify names, values, and repeated entries quickly.
- Inspect redirect links, callback URLs, or tracking URLs to confirm percent-encoded content is correct.
- Turn temporary query strings into structured output before copying, comparing, or adding them to debug notes.
How to use it
- Paste a full URL, a query string that starts with ?, or raw GET parameters such as a=1&b=2.
- Click Format to inspect the parameter table, duplicate counts, and structured JSON output.
- Use Compact when you need a tight query string, or copy the current result for the next debugging step.
