About XML Formatter

An XML formatter helps whenever XML arrives as one long line: a sitemap you're about to submit to Google Search Console or Bing, an RSS feed that won't validate, an SVG exported from a design app, or a config file such as a pom.xml or an Android layout. Paste the XML or open a file, and it's checked and formatted as you type.

The check uses your browser's built-in XML parser. If the document isn't well-formed, you see the error with its line and column, which usually points to an unclosed tag, an unescaped ampersand or a missing quote. Valid XML is indented with 2 spaces, 4 spaces or tabs, keeping comments, CDATA sections and processing instructions, while Minify strips whitespace and comments instead. This is a well-formedness check, not validation against a DTD or XSD schema. For sitemaps, the Sitemap Checker also tests the URLs inside. Nothing is uploaded.

FAQ

XML Formatter: questions and answers

How do I validate XML online?
Paste it or open the file. If it isn't well-formed, you get the error message with its line and column. If it is, you see the formatted XML. Ordinary HTML pages usually fail this check, so format those with the HTML Formatter.
Does the XML formatter validate against an XSD or DTD?
No. It checks that the XML is well-formed, meaning tags are closed and properly nested and attributes are quoted, using your browser's XML parser. Schema validation isn't included.
Are comments and CDATA kept?
Yes. Comments, CDATA sections and processing instructions are kept when the XML is pretty-printed. Minify drops the comments but keeps CDATA.
Can I format an SVG or a sitemap?
Yes, any XML works, including SVG files, RSS feeds, sitemaps and config files. To check the URLs listed in a sitemap, use the Sitemap Checker.
Is my XML uploaded when I format XML online?
No. Parsing and formatting happen in your browser, so nothing is sent to our server, and there's no daily limit.
