About Query String Parser
Reading a long URL query string by eye is error-prone. This tool splits the parameters, URL-decodes the values, and presents them as a tidy JSON object so you can see exactly what a link carries. It is useful for debugging tracking parameters, API calls and redirects, and it runs entirely in your browser.
FAQ
Do I include the leading question mark?
You can include it or not — a leading ? is ignored automatically.
Are values URL-decoded?
Yes — percent-encoded values are decoded so you see the real text.
How do I do the reverse?
Use the query string builder tool to turn a JSON object back into a query string.
