Formatted output will appear here.
Format & Beautify
Pretty-print XML with customizable indentation (2 spaces, 4 spaces or tabs) and syntax highlighting for tags, attributes and values.
Minify
Compress XML by removing all unnecessary whitespace and newlines, reducing file size for storage and network transfer.
Validate
Check your XML for well-formedness errors. The parser detects issues and shows the exact position where the problem occurs.
How to Use XML Formatter
The XML Formatter beautifies and validates your XML documents with proper indentation and syntax highlighting. All formatting happens locally in your browser, so your data stays private. This tool is perfect for working with SOAP APIs, configuration files, RSS feeds, and any XML-based data exchange format.
Open the XML Formatter
Navigate to the XML Formatter from the developer tools section. The tool runs entirely in your browser, ensuring that sensitive XML data such as configuration files or API payloads never leaves your device.
Paste Your XML Content
Paste your minified, unformatted, or messy XML content into the input area. The tool accepts XML of any size and complexity including documents with namespaces, CDATA sections, and processing instructions.
Choose Formatting Options
Select your preferred indentation style (spaces or tabs), indentation size, and whether to preserve or collapse empty elements. These options let you match your project's coding standards.
Format and Review
Click the format button to beautify your XML. The output panel displays the formatted XML with proper indentation, line breaks, and syntax highlighting for easy reading and inspection.
Copy or Download the Formatted XML
Use the copy button to place the formatted XML on your clipboard, or download it as a file. The output is ready to use in your IDE, commit to version control, or share with teammates.
Common Use Cases
SOAP API Development
Format SOAP request and response XML payloads for debugging, logging, and documentation purposes when working with enterprise web services.
Configuration File Management
Beautify XML configuration files for application servers, build tools, and frameworks to improve readability and maintainability during development.
RSS and Atom Feed Inspection
Format RSS or Atom XML feeds to inspect their structure, validate entries, and debug syndication issues with content delivery.
Data Exchange Troubleshooting
Pretty-print XML data exchange documents to identify structural problems, missing elements, or incorrect nesting in B2B integrations.
Pro Tips
- -Validate your XML structure before formatting to catch missing closing tags, mismatched elements, or encoding issues early.
- -Use consistent indentation settings across your team to keep XML configuration files uniform in version control systems.
- -For very large XML files, consider formatting sections individually to maintain browser performance and readability.
- -Pay attention to CDATA sections and comments, as some formatters may alter whitespace within these blocks unexpectedly.
- -Use the minify option when you need to reduce XML payload size for API transmission or storage optimization.
