Frequently Asked Questions

Does it validate XML as well as format it?
Yes. The formatter parses the XML using a DOM parser and will report syntax errors such as unclosed tags, mismatched elements, or invalid attribute syntax before formatting.
What indentation is used?
The default is 2-space indentation, which is the most common convention. The output preserves CDATA sections, processing instructions, and XML declarations.
Can it handle large XML files?
The tool handles XML up to a few MB comfortably in the browser. For very large files (10MB+), consider a desktop XML editor.

About XML Formatter

The XML Formatter makes sense of raw, minified, or poorly formatted XML documents by adding proper indentation and line breaks. XML is widely used in SOAP APIs, RSS feeds, SVG images, Android resources, and configuration files — making a reliable formatter an essential tool for any developer working with these formats.

Beyond beautification, the formatter validates your XML structure and surfaces parsing errors with clear messages. This makes it useful both for making XML readable and for quickly catching structural issues in API requests, configuration files, or data exports.
