XML Validator
Validate XML syntax — checks tag matching, attribute quotes, and well-formedness.
✓ Valid XML — well-formed, all tags match.
How XML validation works
This tool checks that your XML is well-formed: every opening tag has a matching closing tag in the correct order, all attribute values are quoted, and the tag names follow XML naming rules. It does not validate against a DTD or XSD schema — for structure validation you need a full schema.
After fixing errors, you can format your XML with XML Formatter, or convert it to JSON with XML to JSON.
Private & free — this tool runs entirely in your browser.
