The Query String Parser is a focused utility that extracts query parameters from URLs. When analyzing tracking links or API requests, the query variables are chained together with ampersands (&) and are hard to read. This tool parses these parameters, displaying them in a clean key-value table.

Operations run client-side in your browser, keeping your query strings secure.

Why This Tool Is Useful

Clean Parameters View: Read complex analytics parameters blocks in a clean table format.

Auto-Decode values: Automatically translates encoded URL parameters (like '%20' to space) in the table.

100% Private Run: Parse confidential tracking URLs locally in your browser.

Practical Example

A marketer parses an ad landing page URL: '?utm_source=google&utm_medium=cpc&utm_campaign=sale'. The tool outputs a clean table: Key: 'utm_source' | Value: 'google', Key: 'utm_medium' | Value: 'cpc', Key: 'utm_campaign' | Value: 'sale'.

Limitations

Parses query syntax parameters. Does not test if parameters are recognized by your tracking system.
