How to use Query String Parser
- Paste a full URL or only the query string portion after the question mark.
- Run the parser and review decoded keys, repeated values, and empty parameters.
- Copy the JSON output for debugging, documentation, or test fixtures.
Why use Query String Parser
Query strings often carry filters, campaign tags, redirect targets, search terms, and application state. When they get long, it becomes difficult to see which parameter is present or whether a value was encoded correctly.
This parser turns that string into a structured view. It is useful for analytics checks, redirect debugging, API tests, deep-link troubleshooting, and comparing URLs that look similar but behave differently.
Best for Query Parser
- Reading long tracking and filter URLs.
- Debugging repeated or missing parameters.
- Turning URL parameters into JSON fixtures.
Practical notes
- Repeated keys may be handled differently by different backends.
- Decode redirect values carefully before trusting them.
- Watch plus signs and spaces in form-encoded URLs.
