About this tool
URL Query String Parser helps you extract and inspect query parameters from a full URL or raw query string. It is useful for debugging links, checking tracking parameters, testing APIs, reviewing campaign URLs, and understanding how key-value parameters are passed in web requests. It is designed for quick development tasks such as debugging, formatting, validating, encoding, decoding, and inspecting data.
How to use URL Query String Parser
- Paste a full URL or query string into the input area.
- Click Parse Query String.
- Review each parameter and its URL decoded value in the parsed table.
- Check the JSON output for structured data, including arrays for duplicate keys.
- Copy the table or JSON, or download the JSON result if needed.
Why use URL Query String Parser?
Query strings can be difficult to inspect when URLs contain encoded characters, empty values, tracking fields, or repeated keys. This parser turns them into a readable table and JSON so developers, testers, marketers, and support teams can verify parameters quickly without sending the input to a server. This makes it useful when working with APIs, configuration files, logs, databases, web pages, or structured data.
