About XML Formatter

Unformatted XML is nearly impossible to read. This tool parses your XML using the browser's native DOMParser, validates it for well-formedness, and outputs it with proper indentation. Syntax errors are clearly reported with line information. Copy the formatted output or minify it. Everything runs in your browser.
