JSON ↔ Paramètres GET

JSON parameter extraction parses JSON data and extracts all parameter paths and their values. This is useful for debugging API responses, exploring complex JSON structures, understanding nested data formats, or generating test data from JSON samples. The tool shows the full path to each parameter using dot notation.

Paste your JSON data in the input area and click Extract to parse it. The tool will display all parameters with their full paths (e.g., `user.profile.name`) and current values. Nested objects and arrays are fully expanded. Click Copy to copy the extracted parameters, or Clear to start over. All processing happens locally in your browser.

This tool supports: JSON objects and arrays, nested structures (any depth), arrays with indexed access (items[0].name), special characters in keys (escaped), and JSON from API responses, configuration files, or any valid JSON source.
