About HTTP Headers Parser
HTTP messages have headers in "Name: Value" format. This tool takes raw header text (e.g. from browser DevTools Network tab or curl -i) and parses it into a table so you can scan names and values easily. The first line (status or request line) is kept; subsequent lines are split on the first colon.
How to use
- Paste the raw headers (including the first status/request line if you have it).
- Click Parse headers. The table appears below.
Frequently Asked Questions
What format should I paste?
Paste headers as received: one "Name: Value" per line. The first line can be the status line (e.g. HTTP/1.1 200 OK). Empty line starts body.
Is my data sent to a server?
No. Parsing runs in your browser. Your headers never leave your device.
Can I parse request headers?
Yes. Same format: Method path and one header per line. The tool parses any "Key: Value" lines.
