Query String Parser
Convert query strings into readable JSON for UTM, OAuth, filters, redirects, and deep-link debugging.
- Query strings can contain tokens, authorization codes, or state values. Mask sensitive values before sharing.
Convert query strings into readable JSON for UTM, OAuth, filters, redirects, and deep-link debugging. Query String Parser uses Query string or URL (textarea, required) and returns a browser-generated result that can be reviewed before copying.
When to use
Use Query String Parser when your workflow needs convert query strings into readable json for utm, oauth, filters, redirects, and deep-link debugging. Example workflow: ?code=abc&state=xyz&redirect_uri=https%3A%2F%2Fapp.com -> Parameters separated into JSON with key and value..
Input
Enter the data requested by the tool. Fields: Query string or URL (textarea, required). Example input: ?code=abc&state=xyz&redirect_uri=https%3A%2F%2Fapp.com
Output
The tool returns a processed result to copy or review. Example output: Parameters separated into JSON with key and value.. Then use related tools to validate, convert, or continue the same workflow.
- Open the tool and review the expected input type. Fields: Query string or URL (textarea, required).
- Paste, upload, or fill in the requested data in the form. Start from the example pattern: ?code=abc&state=xyz&redirect_uri=https%3A%2F%2Fapp.com.
- Run the processing step and read validation messages if they appear.
- Review the result, copy only what you need, and validate it before production use.
- Debug OAuth parameters: Use Query String Parser in this workflow: ?code=abc&state=xyz&redirect_uri=https%3A%2F%2Fapp.com -> Parameters separated into JSON with key and value..
- url params: Use Query String Parser for url params directly in the browser.
- Invalid or incomplete input: If the tool rejects the input, review these fields and formats before trying again: Query string or URL (textarea, required). Review required fields, accepted formats, and validation messages before using the result.
- Sensitive data: Processing runs in the browser, so review any sensitive data before pasting, uploading, or sharing it. Avoid sharing results until you review tokens, documents, files, or personal data involved.
- Large inputs: Very large files or text can take longer in the browser and should be validated before critical workflows.
Debug OAuth parameters
Input: ?code=abc&state=xyz&redirect_uri=https%3A%2F%2Fapp.com
Output: Parameters separated into JSON with key and value.
Can I paste a full URL?
Yes. The tool extracts everything after ? and ignores the fragment after # while parsing parameters.
Does it show repeated parameters?
Yes. Output includes an ordered list and a grouped object to reveal repeated keys.
Does it work for UTM parameters?
Yes. Use it to review utm_source, utm_medium, utm_campaign, and other tracking parameters.
What happens to encoded values?
URLSearchParams decodes common percent-encoded values, such as spaces and nested URLs.
Is the query string sent to a server?
No. Parsing runs locally in your browser.
How do I use this tool safely?
Use the tool as a short workflow: review the expected input, run processing, and validate the output: Fields: Query string or URL (textarea, required). Example workflow: ?code=abc&state=xyz&redirect_uri=https%3A%2F%2Fapp.com -> Parameters separated into JSON with key and value.. Enter the requested input, run the tool, and review validation messages or warnings before copying the result.
Which inputs and outputs should I check?
