What is URL-encoded JSON?

URL encoding converts characters into a format that can be transmitted over the Internet. In URLs, certain characters like spaces, quotes, and brackets must be encoded. JSON data in URLs appears as strings like %7B%22name%22%3A%22John%22%7D which decodes to {"name":"John"}.

Step-by-Step Usage Guide

  2. Click "Decode Now": Our tool will instantly decode the URL-encoded string and display the formatted JSON.
  3. Validate JSON Structure: Use the "Validate JSON" button to check if your decoded JSON is syntactically correct.
  4. Extract URL Parameters: The tool automatically extracts and displays any URL parameters found in your input.
