Does the formatter change the XML content?

No. The formatter only changes whitespace between elements (indentation and line breaks). Text content, attribute values, and the document structure are preserved exactly as they were. Whitespace within text nodes is not modified.

What happens if the XML is invalid?

The formatter attempts to parse the XML and highlights any structural errors it finds, such as mismatched tags, unclosed elements, or invalid characters. The error location is shown so you can fix the issue in your source and reformat.

Can I format large XML files?

Yes. The formatter handles large XML documents efficiently. Performance depends on the document size, but files up to several megabytes are processed quickly in the browser.

Does the formatter handle XML namespaces?

Yes. Namespace declarations (xmlns) and namespace prefixes are preserved in the formatted output. The formatter treats namespaced elements and attributes the same as non-namespaced ones.

What indentation style should I use?

2 spaces is the most common convention for XML formatting. 4 spaces provides more visual distinction for deeply nested documents. Tabs are used in some team conventions. Choose the style that matches your project's existing code style.
