Our online XML tool helps you format, minify, and validate XML documents. Perfect for working with configuration files, web services (SOAP), RSS feeds, or document markup, this tool instantly transforms XML between compact and human-readable formats.
What is XML?
XML (eXtensible Markup Language) is a markup language that specifies a set of rules for encoding documents in a way that is both human and machine readable.
