XML Formatter

Format, validate, and beautify XML data

About XML Formatter

Our free XML formatter tool helps developers format, validate, and beautify XML (eXtensible Markup Language) data instantly. XML is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It's widely used for data storage, configuration files, web services (SOAP), and document formats.

What is XML?

XML (eXtensible Markup Language) is a markup language similar to HTML but designed to store and transport data rather than display it. XML uses tags to define elements and attributes to provide additional information. Unlike HTML, XML doesn't have predefined tags - you create your own tags based on your data structure.

XML is commonly used for:

  • Data Storage: Storing structured data in a readable format
  • Configuration Files: Application and server configuration
  • Web Services: SOAP and REST API data exchange
  • Document Formats: Office documents, RSS feeds, and more
