Beautify, validate, and minify XML code with syntax highlighting and error detection.
Our XML formatter instantly beautifies, validates, and minifies XML code. Perfect for developers working with configuration files, data exchange formats, or any XML-based documents. Automatically detects syntax errors, validates structure, and provides clear error messages with line numbers.
Formatting: The parser reads your XML and reformats it with proper indentation. Choose between 2, 4, or 8 spaces for indentation. The tool preserves all attributes, comments, and CDATA sections while making the structure readable.
Validation: The built-in XML parser checks for syntax errors, mismatched tags, and invalid characters. If an error is found, it displays the exact location and description, making debugging quick and easy.
Minifying: Remove all unnecessary whitespace to reduce file size while keeping the XML valid. Useful for reducing bandwidth or preparing XML for production environments.
Paste your XML code into the input area and click 'Format'. The tool will beautify and indent the XML properly. You can adjust the indentation size (2, 4, or 8 spaces) using the dropdown menu.
Yes, click 'Validate' to check if your XML is well-formed. The tool automatically validates during formatting and minifying as well. Any errors will be displayed with line numbers and descriptions.
Click 'Minify' to remove all unnecessary whitespace and reduce file size while keeping the XML valid. This is useful for reducing bandwidth or preparing XML for production.
The formatter supports all standard XML features including attributes, comments, CDATA sections, processing instructions, and namespace declarations. Complex nested structures are handled correctly.
There's no strict file size limit, but very large XML files (over 10MB) may take longer to process due to browser limitations. For larger files, consider using server-side formatting tools.
Absolutely. All processing happens locally in your browser. Your XML code is never sent to any server, making it completely safe for sensitive configurations, API responses, or confidential data.
