XML Formatter
Pretty-prints XML with configurable indentation and line breaks, and reports any well-formedness errors.

What XML Formatter does
The XML Formatter on IT Tools accepts raw XML code as input and restructures it into a neatly formatted, human-readable version. It applies configurable indentation and line breaks to improve readability, while simultaneously validating the markup against well-formedness standards. This dual function allows developers to both beautify complex configuration files or API payloads and identify structural errors before implementation. The tool outputs a standardized structure that makes deep nesting easier to inspect and debug. It is designed for anyone needing to quickly organize or verify XML data without installing local software.
