How to Format XML Online in 3 Steps

2

Choose Indentation

Select your preferred indentation level (2 spaces, 4 spaces, or 1 tab) and toggle comment removal.

3

Format & Export

Click "Format XML" to beautify the code. Copy the result directly to your clipboard or download it as a file.

Why Format XML Code?

XML (Extensible Markup Language) files generated by APIs, database exports, or automated build systems are frequently minified into single-line strings to conserve bandwidth. While machine-readable, unformatted XML is extremely difficult for human developers to inspect, audit, or debug.

Formatting XML aligns nested tag elements hierarchically, making structure mismatches, unclosed tags, and syntax errors immediately apparent. Using clean 2-space or 4-space indents maintains consistent coding standards across development teams.
