What Is an XML Formatter?

An XML formatter takes minified or inconsistently indented XML markup and rewrites it with clean, nested indentation, making the document's element hierarchy easy to follow at a glance.

It's particularly useful for XML returned by APIs, RSS feeds, or SOAP services, which is often minified for transport and hard to read without reformatting first.
