XML Formatter & Validator

Format, validate, minify, and convert XML documents. Find syntax errors with detailed error messages.

What is XML?

XML (eXtensible Markup Language) is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. XML is widely used for data exchange between systems, configuration files, web services (SOAP), RSS feeds, and Android app development. Unlike HTML, XML is designed to store and transport data, not to display it.

Our XML tool provides comprehensive functionality including formatting with proper indentation, syntax validation with error detection, minification for production use, and conversion to JSON format. All processing happens client-side, ensuring your data remains private and secure.

Common XML Use Cases

  • Web Services & APIs: SOAP-based web services use XML for request/response messages between systems
  • Configuration Files: Many applications and frameworks use XML for configuration (Maven pom.xml, Android layouts, Spring configs)
  • Data Exchange: XML is a standard format for exchanging data between different systems and platforms
  • Android Development: Android apps use XML for defining user interface layouts and resource configurations
  • RSS/Atom Feeds: Content syndication feeds use XML to distribute blog posts and news articles
  • SVG Graphics: Scalable Vector Graphics (SVG) files are XML-based vector image formats
