What is an XML Formatter?
An XML Formatter (also called an XML Beautifier or XML Pretty Printer) is an online tool that transforms raw, compressed, or unformatted XML data into a clean, readable format with proper indentation and structure. XML (eXtensible Markup Language) is a markup language widely used for data storage, configuration files, web services, and data exchange.
When working with SOAP APIs, RSS feeds, or configuration files, XML data often comes in a single line without any formatting, making it extremely difficult to read and understand. Our XML Formatter instantly converts this messy data into a well-structured, indented format that's easy to scan and analyze.
Did you know? XML has been the backbone of web services and data exchange for decades, used in technologies like SOAP, RSS, SVG, and countless configuration formats across millions of applications.
