Frequently Asked Questions
What is XML formatting?
XML formatting (also called "pretty printing") is the process of adding proper indentation, line breaks, and spacing to XML documents to make them more readable for humans. It doesn't change the data structure, only its presentation.
How does this XML formatter work?
Our XML formatter parses your XML input, validates its structure, then reconstructs it with proper indentation based on your selected settings. It can handle both formatted and minified XML input.
Is my XML data safe?
Yes! All processing happens entirely in your browser. Your XML data never leaves your computer or gets sent to any server. We don't store or collect any of your data.
What XML features are supported?
Our formatter supports standard XML features including elements, attributes, comments, CDATA sections, namespaces, and processing instructions. It validates XML syntax and highlights errors.
Can I format large XML files?
Yes, but performance depends on your browser's capabilities. For extremely large files (10MB+), we recommend using desktop XML tools. This tool works best with files under 5MB.
How do I copy the formatted XML?
Click the "Copy to Clipboard" button in the output panel or use the keyboard shortcut Ctrl+C (Cmd+C on Mac). You can also right-click on the formatted output and select "Copy".
