About this free xml formatter & validator tool
Validate well-formed XML and indent its elements without fetching resources. Developer utilities inspect or transform data locally rather than contacting the address or service shown in your input. Use fictional samples while checking a format, keep credentials out of shared screenshots and validate the result against the receiving system. Successful parsing does not establish trust, security or schema correctness.
A practical example
A concrete example uses input text: <root><a>1</a></root>. The result is <root> <a>1</a> </root>.
Before you rely on the result
DOCTYPE declarations are rejected. XML must be well formed; mixed-content elements are kept intact instead of inserting potentially meaningful whitespace.
