XML Formatter & Validator

An XML Formatter is a layout utility that cleans and formats minified, cluttered XML strings into indented, hierarchical trees. By parsing the XML tags and nesting structures, it applies indentation to separate nested components. This formatter is key for developers working with SOAP APIs, RSS feeds, or Android/IIS config files. Our formatter runs client-side to ensure that your API schemas are processed with complete privacy. Furthermore, the converter maintains exact data types for numbers, booleans, and null fields, ensuring type safety when importing files into database servers or runtime systems. The formatting layouts adhere strictly to official language specifications. With zero server round-trips required, developers can execute large translation tasks instantly without worrying about timeout thresholds, network latency, or upload speed bottlenecks.

Input (Minified): Output (Formatted):

Beyond beautification, our tool checks your XML for structural validity (properly closed tags, valid attributes) and provides an option to minify the output for production use by removing unnecessary whitespace and comments.

XML files often contain enterprise configuration data or legacy system exports. Our tool processes all XML data locally on your device, ensuring that your internal data structures and sensitive attributes are never exposed to external servers.
