What is an XML Formatter?
An XML formatter (beautifier) takes compact, minified or poorly-indented XML and re-formats it with consistent indentation, making the structure and hierarchy immediately readable. It also validates that the XML is well-formed in the process.
Common XML Use Cases
- Formatting API responses from SOAP or REST endpoints that return XML
- Reading and editing configuration files (.xml, .config, .plist)
- Working with RSS and Atom feeds, SVG files, and Android layouts
- Debugging malformed XML before processing it in code
Frequently Asked Questions
Well-formed XML follows the basic syntax rules: every tag is closed, attributes are quoted, and there is a single root element. Valid XML additionally conforms to a specific schema (DTD or XSD). This tool checks well-formedness — the browser's DOMParser validates structure without a schema.
Common issues include unclosed tags, mismatched tag names (case matters), unquoted attribute values, or special characters like & and < inside text content that aren't escaped as & and <.
Yes. The formatter preserves all namespace declarations and prefixes (xmlns:, xsi:, etc.) exactly as written.
