Format, Validate, and Minify XML in One Place
This XML Formatter & Validator takes messy, single-line, or inconsistently indented XML and turns it into clean, readable markup — or compresses it for transport. It also acts as a live XML validator, using your browser's native parser to confirm the document is well-formed and to pinpoint the first syntax error when it isn't.
Well-Formedness Checking
Common XML problems — unclosed tags, mismatched element names, unquoted attributes, or multiple root elements — are caught instantly with a clear message. This is the fastest way to answer "why won't my XML parse?" for SOAP payloads, RSS feeds, config files, Android layouts, and SVG.
Private by Design
Everything runs locally in your browser. Your XML — including sensitive API responses or configuration — is never uploaded, logged, or stored. It also works offline once loaded.
