XML Formatter
Format, validate, and minify XML with syntax highlighting.
About this tool
A fast, browser-based XML formatter that instantly prettifies messy XML with configurable indentation, validates your markup and reports any errors with line numbers, and minifies XML by stripping unnecessary whitespace. Syntax highlighting with color-coded elements, attributes, and values makes large documents easy to read. No data is ever sent to a server — all processing happens entirely in your browser.
