What the XML Formatter does
Transform compressed, one-line XML documents or malformed RSS feeds into neatly indented, human-readable code. Choose your preferred indentation width and beautify nested tag structures instantly.
The tool also validates tag closure syntax, flagging unmatched opening and closing tags so you can repair broken XML schemas before parsing.
Why the XML Formatter is useful
Web services, SOAP APIs, SVG vector graphics, and sitemap files often serialize XML as a single continuous line, making manual debugging impossible.
Hand-indenting nested XML hierarchies with dozens of attributes is tedious and prone to accidental tag deletions.
Also known as: xml formatter, xml beautifier, free xml formatter, online xml formatter, xml formatter online free, xml formatter tool, best xml formatter tool.
