Are CDATA sections handled correctly?

Yes. CDATA sections are preserved exactly as-is, so their inner content is never restructured.

Can it format invalid (non-well-formed) XML too?

XML that isn't well-formed, such as mismatched tags, may be indented differently than expected. Check the original structure first.

Is the content I enter sent to a server?

No. It's processed entirely in your browser.

Can I tidy HTML here?

It works, but HTML has different rules (optional closing tags) — prefer the HTML formatter.

Are attributes or content changed?

No — only indentation and line breaks; tags, attributes and text stay the same.

🎯 Use Cases

Turn a minified XML response into a readable form
Check the structure of config files (pom.xml, etc.)
Debug an XML API response

Example

Input

<config><host>localhost</host><debug enabled="true"/></config>

Output

<config>
  <host>
    localhost
  </host>
  <debug enabled="true"/>
</config>

A one-line minified XML string is indented by two spaces per level to match its tag hierarchy. Text inside an element moves to its own line, and empty (self-closing) tags are kept exactly as written.

XML elements and how they are tidied

Indentation follows tag nesting depth. Unlike HTML, XML requires every tag to close and is case-sensitive.

Element	Handling
Open/close tags	Indented by nesting depth
Self-closing tags	`<tag />` kept on one line
Attributes	Left untouched inside the tag
Comments & CDATA	Content preserved as-is
