Indents and validates XML so it's easy to read.

Frequently asked questions
Does it validate XML syntax?▼
Yes. The tool parses your XML and reports well-formedness errors including mismatched tags, unclosed elements, and invalid characters. Valid XML is formatted with consistent indentation.
Can it handle large XML files?▼
The tool handles files of several megabytes comfortably in modern browsers. Extremely large files (50MB+) may be slow to parse depending on your device's memory and processing power.
Does formatting change the XML semantics?▼
No. Formatting only adds or adjusts whitespace between tags. Element content, attributes, namespaces, and document structure are preserved exactly as-is.
