HTML Formatter

HTML Formatter re-indents tags, attributes, and nested structures so templates, email fragments, and scraped markup become readable for review and diffing.

It accepts typical HTML5-style markup from WordPress themes, React SSR output, and legacy table layouts.

Production HTML arrives minified from build tools—support engineers need readable markup to find a missing closing div.

Email developers paste inline-CSS HTML from clients—formatting exposes broken nested tables fast.

• Beautify Laravel or Rails view partials during review
• Format HTML email templates before Litmus testing
• Inspect scraped competitor landing page structure
• Clean Jekyll or Hugo template fragments
• Prepare tutorial code snippets for documentation sites

1. 1Paste minified or messy HTML into the input area.
2. 2Choose indent size if the workspace exposes options.
3. 3Click Format and review nested structure in the output panel.
4. 4Copy formatted HTML into your IDE or CMS.
5. 5Use HTML Minifier when you need production-ready compact output again.

• Inline scripts and styles may reformat awkwardly—exclude sensitive blocks when pasting public examples.
• Pair with HTML Encoder when displaying HTML as text in documentation.
• Validate rendered output in a browser after formatting—indentation does not guarantee valid DOM.
• Do not format untrusted HTML with scripts enabled in preview panes on other sites—this tool formats text only.

• Malformed HTML may be “repaired” differently than browsers expect—validate in devtools.
• Very large single-line documents may slow the formatter.
• Common mistake — formatting HTML with template placeholders: ensure {{ }} or <% %> blocks stay intact.
