Frequently Asked Questions

What is XML formatting?
XML formatting (also called beautifying) adds proper indentation and line breaks to make XML code more readable. It organizes nested elements hierarchically, making the structure clear and easier to understand for developers and analysts.
Is my XML data safe?
Absolutely! All XML processing happens entirely in your browser using JavaScript. Your XML data is never uploaded to any server or stored anywhere. This ensures complete privacy and security for sensitive configuration files or data.
What's the difference between format and minify?
Format adds indentation and line breaks for readability (useful for development), while minify removes all unnecessary whitespace to reduce file size (useful for production). Both preserve the XML structure and data integrity.
Can this tool validate XML syntax?
Yes! The tool automatically validates XML syntax as you type and displays real-time error messages. It checks for well-formedness including matching tags, proper nesting, and valid XML structure using the browser's DOMParser.
Can I process multiple XML files at once?
Yes! Upload multiple XML files by dragging them into the drop zone or selecting multiple files. The tool will process all files and let you download them individually or all at once with the "Download All" button.
