HTML Formatter
Format HTML code (best-effort).
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
- Paste your HTML into the input field.
- Run the formatter and scan the indented output.
- Fix any structural issues you notice (missing closers, accidental nesting).
- 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.
