XML Syntax Checker

XML Syntax Checker

Check XML well-formedness and serialize the parsed document.

Try the sample, paste your own input, or load a local file where offered.

How to use this tool

This is a syntax check, not XSD validation. DTD declarations are rejected. Formatting preserves text nodes rather than inserting potentially meaningful whitespace.

Your inputs and files are processed in this browser. This tool does not send them to a server or save an input history. Copy or download any results you want to keep.
