How to format XML

Paste your XML, open a file, or drop one onto the box. SVG, XSD, WSDL and .config files work too.
The indented result appears on the right as you type.
If something is wrong, such as a tag that isn't closed, you'll see the line and column. Press Format / validate to jump there.

What does "well-formed" mean?

Every tag is closed, tags are nested properly, there is exactly one root element, attribute values are in quotes, and special characters like & are written as &.

Does it check my XML against a schema (XSD)?

No. It checks that the XML is well-formed, not that it follows a particular schema.

Are comments and CDATA kept?

Yes. Comments, CDATA sections, processing instructions and the <?xml ?> declaration are kept.
