How to use the XML Formatter

  1. Paste your XML into the left box, or open a file.
  2. Adjust the options if you need to.
  3. Copy the formatted XML or download it as a file.

What does this tool do?

Your browser's XML parser checks that the document is well-formed (every tag closed, attributes quoted, one root element). Comments, CDATA sections and processing instructions are preserved.

Why use it?

  • Read sitemaps, feeds and SVG files.
  • Spot unclosed tags.
  • Minify XML for transport.

Well-formed vs valid

“Well-formed” means the XML follows syntax rules. “Valid” additionally means it matches a schema (XSD or DTD). This tool checks well-formedness.

Privacy
