About XML Formatter & Beautifier
The XML formatter pretty-prints, minifies and validates XML documents in the browser. Beautify mode re-indents nested elements with your chosen indent — two spaces, four spaces or tabs — while Minify strips inter-element whitespace to produce the smallest well-formed output.
Validation runs as you type: well-formed documents get a "Valid XML" badge with node and line counts, while malformed input is flagged with the approximate error line, so you can find an unclosed tag or stray ampersand quickly. That makes the tool double as a lightweight XML validator for config files, sitemaps, RSS feeds and SOAP payloads.
Everything happens locally — your XML never leaves your device, which matters for configuration files containing credentials or internal URLs. Copy the result or download it as formatted.xml.
