XML Toolkit

Free Online XML Tools

Everything you need to work with XML — format, validate, convert, escape, and generate code. All 39 tools run client-side.

What Is XML and When Should You Use It?

XML (eXtensible Markup Language) is a structured, self-describing data format widely used in enterprise systems, SOAP web services, document storage, configuration files (Maven, Android, .NET), and data interchange between legacy platforms.

Our XML toolkit provides everything you need to work with XML — format messy markup, validate structure, convert to modern formats like JSON or YAML, and generate typed code classes for multiple languages.

Common Use Cases

  • check_circleFormat and prettify XML responses from SOAP APIs
  • check_circleValidate XML config files for Maven, Android, or .NET projects
  • check_circleConvert XML data to JSON for use in modern web apps
  • check_circleParse WSDL files to understand SOAP service contracts
  • check_circleEscape XML strings for safe embedding in HTML or attributes
  • check_circleGenerate Java or C# data classes from an XML schema sample
  • check_circleMinify XML to reduce payload size in web services

Frequently Asked Questions

What is the difference between XML and HTML?

HTML defines a fixed set of tags for displaying web content. XML is extensible — you define your own tags to describe any data structure, making it suitable for data interchange rather than presentation.

What are WSDL and SOAP?

WSDL (Web Services Description Language) is an XML format that describes a SOAP web service interface. SOAP is a protocol for exchanging structured messages over HTTP, commonly used in enterprise integrations.

Can I convert XML to JSON without losing data?

Yes. Our XML to JSON converter preserves attributes, nested elements, and text content. Complex structures like mixed content may require minor manual adjustment after conversion.

What languages can I generate from XML?

Our Data to Class generators support Java, Python, TypeScript, C#, Go, Rust, Swift, and Kotlin — producing typed data models from your XML structure.
