Cookie Parser

Understanding HTTP Cookies

HTTP cookies help websites remember sessions, authentication states, user preferences, analytics data, shopping carts, and other browser-related information. Modern websites and APIs often rely on cookies for login systems and session management.

During debugging workflows, cookie headers can become difficult to inspect manually because multiple values are packed into a single string. This parser converts raw cookie headers into structured key-value pairs so they are easier to read, analyze, and debug.

The tool works entirely inside your browser and is useful for API testing, authentication debugging, browser inspection, frontend development, and session troubleshooting.

How to Use the Cookie Parser

1. Copy the cookie header from your browser or API request.
2. Paste the cookie string into the input box.
3. Click Parse Cookies.
4. Review the parsed cookie values in structured JSON format.
5. Copy the parsed output for debugging or development workflows.

Common Use Cases

• Debugging login sessions and authentication systems.
• Inspecting browser cookie storage and session values.
• Analyzing cookies used in API requests and responses.
• Reviewing analytics and tracking cookie values.
• Debugging JWT-based authentication workflows.
• Inspecting URL encoded cookie values.
• Testing session-based applications and dashboards.

Example Cookie Header

session_id=abc123;
theme=dark;
logged_in=true;
csrftoken=x7a91d;
auth_token=eyJhbGciOi...

{
  "session_id": "abc123",
  "theme": "dark",
  "logged_in": "true",
  "csrftoken": "x7a91d",
  "auth_token": "eyJhbGciOi..."
}
