What Is XML Formatter?
XML Formatter is a free online xml formatter that beautifies and validates XML documents instantly. Paste your XML to get properly indented, readable output with error detection for malformed documents.
Key Features
Format XML with proper indentation and line breaks. Validate XML structure and report errors. Minify XML to reduce file size. Syntax highlighting for easy reading. Copy formatted or minified output with one click.
Benefits of Formatting XML
XML documents can be deeply nested and difficult to read without proper formatting. A formatter reveals the document structure, making it easy to find elements, check nesting, and verify that the data is correct before processing.
Common Use Cases
Format API responses that return XML data. Clean up configuration files like Maven pom.xml or Android layouts. Inspect SOAP web service messages. Validate XML before importing into databases or applications. Prepare XML samples for documentation.
XML Best Practices
Use meaningful element and attribute names. Keep nesting levels manageable. Validate XML against a schema (XSD) when structure matters. Use CDATA sections for content that contains special characters. Consider JSON for new APIs unless XML is specifically required.
