Organize group expenses with the agility of a spreadsheet.
Paste the header section copied from a network inspector, request example, or raw HTTP response. Repeated header names stay grouped as arrays.
The HTTP Header Parser Builder converts raw header text into structured JSON and can rebuild header blocks from JSON when you need to paste them back into code samples, test fixtures, or API documentation.
Paste headers from browser devtools, curl examples, or server logs to turn them into a readable JSON object. When the same header appears more than once, the tool keeps those values in arrays instead of collapsing them into a single string.
Builder mode accepts either a plain JSON object of headers or a wrapper with startLine and headers fields. This makes it easy to regenerate request examples, mock response snippets, and integration-test fixtures from structured data.
Some headers such as Set-Cookie need separate lines for each value. Keeping repeated values in arrays helps avoid invalid merges and preserves the shape you actually need in real HTTP traffic.
