Extract hidden input names and values from pasted HTML forms before endpoint mapping, migration review, QA fixture work, or documentation cleanup.
Use Extract Hidden Input Fields when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste form markup, checkout snippets, rendered component HTML, or QA fixtures containing hidden inputs.
- Choose whether duplicate hidden-field rows should be removed and whether field names or values should be normalized.
- Review hidden input names and values with source lines, then copy the list for endpoint mapping, migration review, test fixtures, or QA notes.

Why extract hidden inputs?
Hidden fields often carry submission metadata, IDs, flags, and fixture values, so extracting them helps endpoint mapping and migration QA.
