About this tool
Paste XML to format it with consistent indentation, or switch to Minify to remove whitespace for a compact version. The tool parses the document itself (no external library) and reports the exact line and column of a syntax error, such as a mismatched tag or an unclosed attribute.
🔒 Your input stays in your browser and is never sent anywhere.
Frequently asked questions
Does this validate against a schema (XSD or DTD)?
No, it checks that the XML is well-formed (correctly nested tags, valid attributes, proper entities), not that it matches a specific schema.
What happens to comments and CDATA sections?
They are kept as-is. CDATA content is never parsed as markup, and comments are preserved in their original position.
