Format XML with a real validity check
This XML formatter and validator handles API responses, configuration files, sitemaps and SVG markup. Invalid input is stopped before formatting so malformed output is not mistaken for a valid document.
Minification removes whitespace between elements. For documents with mixed text and child elements, confirm that whitespace is not part of the intended content.
Frequently asked questions
Does this tool validate XML?
It checks whether the browser can parse the document and reports parser errors before producing output.
Does formatting change the XML data?
It changes whitespace between elements. Mixed-content XML, where spaces inside text are meaningful, should always be reviewed.
Can it format SVG?
Yes. SVG is XML, so valid SVG markup can be formatted or minified.
Is XML sent to a server?
No. Validation and formatting happen locally in your browser.
