What is Query String Parser?
Query String Parser breaks down the query string portion of a URL (everything after “?”) into key-value pairs and lists them. Values are automatically URL-decoded, and the result can be converted to JSON with one click. Useful for debugging API requests and inspecting complex query parameters.
How to Use
- Paste a query string (?key=value&...) or a full URL into the input field.
- With auto-parse enabled, parameters are listed instantly as you type.
- Each parameter is shown with its key and URL-decoded value.
- Click "Copy as JSON" to copy the result as JSON to the clipboard.
FAQ
Can I enter a full URL instead of just a query string?
Yes. If you enter a full URL, only the query portion is automatically extracted and parsed.
What happens with duplicate keys?
The table lists each occurrence as a separate row. In the JSON output, duplicate keys are grouped into an array.
Are values URL-decoded?
Yes. Encoded values such as %20 or plus signs are automatically decoded for display.
Is my data sent to a server?
No. All processing happens in your browser using the built-in URLSearchParams API.
