HTML Form Field Extractor

How to use this developer tool

1. Paste source text or load the representative sample.
2. Adjust the available parsing option when the tool provides one.
3. Select Extract Fields or press Ctrl/Cmd + Enter.
4. Review the summary, issues, and copy-ready output before using it.

What this developer tool does

The markup is parsed in an isolated HTML document. Each input, select, textarea, and button is inspected in source order; labels are resolved from wrapping labels, for attributes, aria-label, and placeholders.

Disabled and unnamed controls are still reported because they can explain gaps between the page and the submitted payload.

Example

Input

<form action="/signup" method="post">
  <label>Email <input type="email" name="email" required autocomplete="email"></label>
  <select name="plan"><option value="free">Free</option><option value="pro">Pro</option></select>
  <textarea name="notes" placeholder="Optional notes"></textarea>
  <button type="submit">Create account</button>
</form>

Expected result

Run the sample to see a structured report generated by the same processing logic used for pasted input.

Use cases

• Review front-end source during a code migration.
• Create a structured handoff for documentation or QA.
• Catch input-specific issues before committing generated output.

Tips for reliable output

• Paste the smallest complete fragment that reproduces the case.
• Use the sample once to confirm the expected input shape.
• Review warnings instead of treating a clean report as a guarantee.
• Keep the original source in version control before replacing it.
• Test generated output in the target browser or application.
