Frequently Asked Questions
How do I format XML?
Simply paste your XML into the text area. The tool will automatically validate and format it with proper indentation. You can choose between 2 or 4 space indentation.
How do I know if my XML is valid?
The tool automatically validates your XML as you paste it. You'll see a green checkmark for valid XML or a red X with an error message for invalid XML.
Can I minify XML?
Yes! Use the mode toggle to switch between Format and Minify modes. Minify mode removes all unnecessary whitespace for compact storage.
What is the XML tree structure view?
The tree structure view shows your XML document's hierarchical structure, making it easy to understand complex nested elements and their relationships.
Is my XML data private?
Absolutely. All formatting and validation happens in your browser. Your XML never gets sent to any server, ensuring complete privacy.
Can I download the formatted XML?
Yes! You can download both the formatted and minified versions as .xml files using the download buttons.
What types of XML can I format?
This tool can format any well-formed XML document, including XML with attributes, CDATA sections, processing instructions, and complex nested structures.
How is XML different from JSON?
XML (eXtensible Markup Language) uses tags to structure data and supports attributes, while JSON uses key-value pairs. XML is often used for configuration files and data exchange in enterprise systems.
