What is HTTP Headers Parser?

Raw HTTP headers can be difficult to read when copied directly from browser dev tools or terminal outputs. This tool takes that raw text block and parses it into a clean, structured JSON object, allowing for easy inspection of Cache-Control, Content-Security-Policy, Cookies, and other vital metadata. It is a must-have for web performance and security auditing.
