HTTP Headers to JSON Parser

When debugging CORS issues, cache policies, or API authentication, developers often copy massive blocks of raw HTTP headers from their browser's Network tab or Curl output. Our HTTP Headers Parser instantly cleans up that raw text block and converts it into a perfectly formatted JSON object.

Why Parse Headers into JSON?

Easy Reading: JSON format allows for syntax highlighting, making it vastly easier to read through dozens of AWS or Cloudflare response headers.
Script Testing: Need to mock an API response? Paste the real headers here to generate a JSON object you can immediately use in your automated tests.
Documentation: Clean JSON objects look much more professional when pasted into Jira tickets or GitHub issues for bug reports.

Privacy

HTTP headers frequently contain Authorization: Bearer ... tokens and sensitive Cookie data. Because our tool is a client-side parser, your private tokens and session cookies never leave your machine.

How to use HTTP Headers Parser

This tool contacts an outside service to do its job, so the input you submit is sent there. We do not store it.

Use it from the API

Everything this page does is also available as a REST endpoint, so you can call HTTP Headers Parser from your own code, a script or a CI pipeline.


Bash
curl "https://api.toolsxpo.com/v1/http-headers-viewer" \
  -H "Authorization: Bearer txp_live_YOUR_KEY"

The endpoint returns a JSON envelope ({ ok, data, meta }) and costs 2 credits per successful call. Try it in the playground or browse the full API reference.
