What is a headers parser for?
It converts HTTP header blocks into JSON so cache, CORS, redirects, cookies, content-type, and security headers are easier to review.
Can I paste headers copied from curl?
Yes. Paste lines in Name: value format. Lines without a colon are ignored.
Does it validate CORS or CSP policy?
No. It structures headers for reading; final policy interpretation stays with you.
How are repeated headers handled?
The output keeps the original order and also groups repeated values by normalized header name.
Are headers sent to a backend?
No. Parsing runs locally in your browser.

Enter the requested input, run the tool, and review validation messages or warnings before copying the result.
