Why Format XML?

XML data returned by APIs or generated by systems is often minified into a single line to save space. Formatting XML adds proper indentation and line breaks, making the hierarchical node structure readable for humans.

How to Beautify XML

Paste your raw XML string into the left editor. The tool parses the markup and outputs a beautifully indented, syntax-highlighted XML document on the right.

Frequently Asked Questions

What does an XML Formatter do?

An XML Formatter takes unformatted, minified, or messy XML code and organizes it by adding proper indentation and line breaks. This makes the nested tree structure of the XML document easy for humans to read and understand.

Is it safe to format sensitive XML data?

Yes. This tool runs 100% locally in your web browser. Your XML data is never uploaded, stored, or processed on our servers.

How do I use the 'Collapse Short Elements' feature?

When enabled, elements that contain only short text and no child elements (e.g., <name>John</name>) will be kept on a single line to save vertical space. When disabled, the opening tag, text, and closing tag will each get their own line.
