About the HTML Formatter

This HTML Formatter indents and structures markup so nested tags are easier to read, review, and debug. Messy one-line HTML from a CMS export or minified template is hard to edit safely; formatting restores a clear hierarchy without changing the meaning of the markup.

Paste HTML, run the formatter, then copy the readable result back into your editor. It is a best-effort beautifier for everyday snippets — not a full browser HTML5 conformance suite.

When to format HTML

  • Cleaning exports before editing modules or email templates
  • Reviewing nested lists, tables, and component markup
  • Preparing a snippet for a code review or documentation page
  • Spotting unclosed tags that are hard to see in a single long line

How to use

  1. Paste your HTML into the input field.
  2. Run the formatter and scan the indented output.
  3. Fix any structural issues you notice (missing closers, accidental nesting).
  4. Copy the result into your project or CMS.

Tips

  • Keep scripts and style blocks intact; review them after formatting if your template is sensitive.
  • If the page relies on significant whitespace inside <pre> or text nodes, verify those areas after beautifying.
  • Pair with the HTML Minifier when you are ready to ship a compact version.

FAQ

Will formatting fix invalid HTML? It improves readability. Broken tags still need a manual fix or a validator.
