About XML Formatter

This tool formats XML with proper indentation for readability, minifies XML for production use, and validates the document structure. Paste any XML — from API responses, config files, or exports — and get properly formatted output.

Frequently Asked Questions
What is well-formed XML?
Well-formed XML follows basic syntax rules: a single root element, properly nested and closed tags, quoted attribute values, and correct entity usage.
What is the difference between XML and HTML?
XML is strict (must be well-formed) and is designed for data transport. HTML is lenient and designed for display. XHTML combines both — HTML with strict XML rules.
Can this handle large XML files?
Yes, the tool handles XML documents of reasonable size. For very large files, consider a local XML tool.
Does formatting change the XML data?
No. Formatting only adds indentation whitespace. The actual data content and structure remain identical.
