XML Formatter

Format and validate XML documents

How to use

1. Paste your XML, minified or messy.
2. It's validated and re-indented into clean, nested markup.
3. Copy the formatted XML back into your project or feed.

Why use this tool

• Format & validate: Pretty-print XML with proper nesting and catch malformed tags.
• Any XML: Works with config files, RSS/Atom feeds, SOAP, SVG, and more.
• 100% private: Everything runs in your browser. Your data is never uploaded to a server, so it's safe for confidential content.

Frequently asked questions

Will formatting change my XML's meaning?

No. Only whitespace and indentation change; elements, attributes, and order are preserved.

Why is my XML invalid?

Common causes are unclosed tags, mismatched names, or stray characters before the root element. The error points to the problem.

Is my XML private?

Yes. Formatting runs in your browser; nothing is uploaded.
