What is HTTP Header Parser?
HTTP Header Parser turns raw request or response header lines into structured JSON. This makes copied network output easier to search, compare, document, and feed into other developer tools while preserving the relationship between each header name and its value.
How to use HTTP Header Parser
Paste raw HTTP headers and convert them into structured JSON for easier inspection or reuse.
When is HTTP Header Parser useful?
HTTP Header Parser is useful when debugging API calls, reviewing proxy output, examining response metadata, or transforming copied headers into structured data.
Example
A practical example is parsing a block of response headers to inspect cache-control, content-type, and request identifiers.
Practical notes
Header values may expose cookies, bearer tokens, internal hosts, tracing identifiers, and infrastructure details. Redact sensitive entries before sharing the parsed output, and account for repeated headers whose meaning cannot always be represented by one simple string value.
