What if my XML isn't well-formed?

You still get formatted output, with a note naming the problem and where it is. That is deliberate: a formatter that refuses to work on broken input is useless exactly when you need it, since indentation is often how you spot the missing tag in the first place.

Can it format an XML sitemap?

Yes, and that is the most common use. Search engines serve sitemaps minified, so ` … … ` arrives as one line. Formatted, each URL becomes a readable block — and if the sitemap is malformed, you find out why.

No. Everything happens in the page, in JavaScript. Nothing is sent to a server, which matters when the XML is an internal config file or a SOAP response with credentials in the header.

XML Formatter

Turn a single unbroken line of XML into something with visible structure. Sitemaps, RSS feeds, SOAP responses and build configs all arrive minified, and the nesting is the only thing you actually need to see. Leaf elements like <loc>https://example.com/</loc> are kept on one line rather than being exploded across three, which is the difference between a formatted sitemap you can scan and one that is longer than the original.

XML Formatter — frequently asked questions

In almost every case, no — whitespace between elements is insignificant to an XML parser. The exception is mixed content, where text and elements share a parent and the spaces between them are part of the text. Whitespace inside a text run is collapsed here, so don't run this over XML where that whitespace is data.
