About this utility
How to use HTTP Header Parser
Parse an HTTP header block into a normalized local report and flag credential-bearing fields.
What to provide
Paste header lines in “Name: value” form. An optional request or status line is recognized separately.
- Paste, type, or drag and drop a supported text file into the input area.
- Review the input and the clearly labeled output behavior.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
Normalized names, duplicate values, start line, and header counts.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- Obsolete folded lines and binary HTTP/2 or HTTP/3 framing are rejected. Header semantics are summarized but not policy-validated.
