What is an XML Formatter and Why Use One?
An XML formatter is an essential tool for developers, data analysts, and system administrators who work with XML documents regularly. Our free online XML beautifier transforms messy, unreadable XML code into properly formatted, indented, and organized markup that's easy to read, debug, and maintain.
Whether you're working with configuration files, API responses, data feeds, or complex XML schemas, proper XML formatting improves code readability, reduces errors, and makes collaboration easier. Our XML minifier also helps optimize XML for production by removing unnecessary whitespace and comments.
