Frequently Asked Questions
What is XML formatting?▼
XML formatting adds consistent indentation and line breaks to XML documents, making the nested tag structure easy to read. Each child element is indented one level deeper than its parent.
Does this tool validate XML?▼
Yes. The tool uses the browser's DOMParser which validates XML syntax. If your XML has errors (unclosed tags, mismatched elements, invalid characters), the tool will display a descriptive error message.
Can it handle large XML files?▼
The tool can handle XML files up to several megabytes. Very large files may take a moment to process since everything runs in your browser. For files larger than 10MB, consider using a desktop XML editor.
Is my XML data secure?▼
Yes. All processing happens entirely in your browser. No data is sent to any server.
