Pro Tips

  • 💡Always ensure your XML has a proper root element - XML requires exactly one root.
  • 💡Use minified XML for API payloads to reduce bandwidth usage.
  • 💡The editor supports code folding - click arrows next to elements to collapse sections.
  • 💡Pay attention to case sensitivity - XML tags are case-sensitive.

Common Examples

Beautify compact XML

Input
<catalog><book id="1"><title>Example</title></book></catalog>
Output
<catalog> <book id="1"> <title>Example</title> </book> </catalog>

Indentation exposes the parent-child structure without changing element values.

Preserve an XML comment

Input
<root><!-- keep this note --><value>1</value></root>
Output
<root> <!-- keep this note --> <value>1</value> </root>

Formatting keeps comments instead of silently removing document content.

Escape reserved characters

Input
<message>Tom & Jerry</message>
Output
<message>Tom &amp; Jerry</message>

A bare ampersand is invalid XML. Replace it with &amp; before formatting.

Frequently Asked Questions

Is my XML data secure?
Absolutely! All XML processing happens in your browser. Your data is never sent to any server.
Why is my XML showing as invalid?
Common XML errors include: unclosed tags, mismatched tag names (case-sensitive), special characters not escaped (&, <, >), and missing root element.
Can I format XML with namespaces?
Yes! The formatter fully supports XML namespaces, including default namespaces and prefixed namespaces.
Does it handle CDATA sections?
Yes, CDATA sections are preserved and properly formatted in the output.
What's the maximum XML size supported?
There's no strict limit, but for best performance we recommend files under 5MB. Very large files may slow down your browser.
