About XML Formatter
Format XML online with this free XML formatter and beautifier, or minify XML to strip whitespace for production use. Paste a document and get consistent indentation for elements, attributes, and nested nodes so large XML files, SOAP envelopes, sitemaps, RSS feeds, and Maven or .NET config become readable. Malformed markup is flagged so you can fix missing tags or broken structure quickly instead of hunting through a single long line.
An XML beautifier is useful when a SOAP response arrives minified, when a sitemap is hard to review, or when you need to paste XML into a ticket with clear hierarchy. Minify when you want a compact payload for a request body or a smaller file to store. Developers working with legacy services, RSS, Atom, Android layouts, or office XML will reach for a formatter more often than a full IDE.
The tool focuses on whitespace and readability. It does not silently drop attributes or rewrite namespaces. Load a file or paste from the clipboard, format, copy, and continue. If the markup cannot be parsed, the status message tells you so you do not copy broken XML into a system that will fail later.
Formatting is done entirely in your browser without uploading your XML. Contracts, invoices, and internal config stay on your device. Use this free online XML formatter, XML beautifier, and XML minifier whenever you need clean, indented markup with privacy.
