How the URL Query Parser Works

Paste a full URL into the input field and the tool extracts every key/value pair from its query string. The rest of the URL — protocol, host, path, and fragment — is ignored so you can focus on the data being passed.

Paste a URL such as https://example.com/search?q=hello&page=2.
Switch between Table, JSON, and JS Object views to see the parameters in the format you need.
Use the Copy button to copy the active view to your clipboard.

Output Formats

Table: A two-column view with parameter names on the left and values on the right — perfect for quickly scanning what a URL is sending.
JSON: A clean JSON.stringify-style block, ready to drop into a config file, an API request, or a test fixture.
JS Object: A JavaScript object literal with unquoted keys where possible, ideal for pasting straight into source code.

What It Handles

Full URLs with protocol, host, path, and fragment.
Bare query strings starting with ? or even just key=value&other=1.
URL-encoded values are automatically decoded so spaces, accents, and symbols read naturally.
Repeated keys like ?tag=a&tag=b are grouped into arrays in the JSON and JS Object views.
Fragments (#section) are stripped — only the query string is parsed.

Common Use Cases

Debugging: Quickly inspect the parameters a frontend or third-party service is sending.
Marketing: Audit UTM parameters and campaign tags on tracked links.
Development: Convert a real URL into JSON or a JS object to seed tests, mocks, or fixtures.
Analytics: Pull apart long redirect URLs to see which parameters are being forwarded.

Privacy and Security

Every URL you paste is parsed locally in your browser. Nothing is sent to a server, logged, or stored — close the tab and the data is gone.
