HTML Prettify Examples

Review practical HTML Prettify examples so you can understand expected input, output, and common patterns faster.

Why examples matter for HTML Prettify

Use this HTML Prettify tool to format raw or minified HTML into a readable structure. It is useful for inspecting copied markup, debugging templates, cleaning generated HTML, reviewing nested elements, and making front-end code easier to scan before editing or sharing.

Example pages are especially useful for developer tools because they show what good input looks like, what kind of output to expect, and how the tool behaves in common scenarios.

HTML Prettify examples

Prettify a compact div block

Input

<div><h1>Hello</h1><p>World</p></div>

Output

<div>
  <h1>Hello</h1>
  <p>World</p>
</div>

Useful when copied HTML is all on one line and hard to read.

Prettify nested list markup

Input

<ul><li>One</li><li><strong>Two</strong></li></ul>

Output

<ul>
  <li>One</li>
  <li>
    <strong>Two</strong>
  </li>
</ul>

Makes nested structures easier to inspect before editing.

How to use these examples

  1. Paste HTML into the input box
  2. Click Run Tool to format the markup
  3. Review the indented output with line breaks
  4. Check the nested structure and tags more easily
  5. Copy the formatted HTML for editing, debugging, or documentation

Common mistakes in sample input

Pasting HTML fragments with broken tags

Fix: Check whether every opening tag has a matching closing tag before formatting.

Expecting the tool to validate every HTML rule

Fix: Use it mainly for readability. It formats structure, but it is not a full validator.

Formatting template syntax mixed into HTML

Fix: Review framework placeholders or server-side template syntax after formatting.
