Frequently Asked Questions
What is the XML Formatter?
The XML Formatter is an online format converter that formats and beautifies XML code for readability. It runs entirely in your browser with no data sent to any server.
What indentation rules does the formatter use?
The formatter uses 2-space indentation for each nesting level. Opening and closing tags are placed on separate lines, and child elements are indented relative to their parent. This produces clean, consistently formatted XML output.
What happens when the XML contains errors?
When invalid XML is detected, the formatter displays an error message indicating the type and location of the problem. The original input is preserved so you can fix the error and try again. Common errors include unclosed tags and malformed attributes.
Can the formatter handle large XML files?
The tool processes XML entirely in your browser using client-side JavaScript. It can handle files of several megabytes without issues. For extremely large files, browser memory may become a limiting factor.
Does the formatter preserve XML comments?
Yes. XML comments (<!-- ... -->) are preserved during formatting. They are placed on their own line with proper indentation, maintaining their position relative to the surrounding elements.
