What is XML formatting?

XML formatting adds proper indentation, line breaks, and consistent structure to XML documents. This makes it easy to read the hierarchy of elements, attributes, and nested content.

Does this tool validate XML?

Yes. The xml formatter checks for well-formedness errors like mismatched tags, unclosed elements, and invalid characters. If your XML has errors, the tool reports them so you can fix the issues.

Can I minify XML with this tool?

Yes. You can switch between beautified and minified views. Minifying removes all unnecessary whitespace, which is useful for reducing XML file size before transmission.

What is the maximum XML file size I can format?

The tool handles XML documents of several megabytes. Processing happens in your browser, so performance depends on your device. For extremely large files, consider using a desktop XML editor.

Does formatting change my XML data?

No. Formatting only adjusts whitespace and indentation. Your element names, attributes, text content, and document structure remain unchanged.

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.
