What this tool does

HTML Form Extractor inventories forms from a page, template, or saved HTML file. It finds each `<form>`, reads method and action, extracts input, select, textarea, and button fields, maps basic `<label for>` text, marks required fields, records autocomplete attributes, counts password fields, and flags practical risks such as password fields submitted with GET, external form actions, empty actions, missing CSRF-style hidden tokens on POST forms, and password fields without autocomplete hints.

Use it during frontend QA, security review, migration planning, analytics instrumentation, or when inheriting a legacy template. The Markdown report gives a human-readable checklist, CSV output becomes a field inventory, and JSON output keeps the same structure available for scripts.

How HTML Form Extractor fits into your work

Use it in the small gaps between coding, reviewing, debugging, and shipping.

Developer jobs

  • Formatting, validating, shrinking, or inspecting code-adjacent text.
  • Preparing snippets for documentation, tickets, commits, or handoff.
  • Checking a small payload quickly without switching tools.

Developer checks

  • Run irreversible transforms like minify or obfuscate on a copy.
  • Keep secrets out of pasted snippets unless the tool explicitly stays local.
  • Use your normal tests or linter before shipping transformed code.

  1. 1 HTML Table to CSV Converter HTML table to CSV converter — paste HTML or full page source, extract all tables, get CSV/TSV/JSON/Excel-ready output with header detection + colspan/rowspan handling. Open
  2. 2 HTML to Markdown HTML to Markdown — paste rich content, get clean .md with links, code, tables, lists preserved. Open
  3. 3 HTML Minifier Minify HTML — strip comments, whitespace, optional attributes, inline CSS/JS. 40-60% smaller. Open

Real-world use cases

  • Audit a signup form before launch

    Paste the HTML and check password handling, autocomplete hints, required fields, and CSRF-style hidden tokens.

  • Build a migration inventory

    Export all legacy template fields as CSV before rebuilding the forms in a new frontend.

Common pitfalls

  • JavaScript-rendered forms are only detected if they exist in the provided HTML.

  • A CSRF hidden field name is a heuristic, not proof that the backend protection is correct.

Privacy

Form extraction is local. Field names, hidden inputs, and actions may reveal internal routes or product details.
