    Why Use XML Formatter?

    Why Use XML Formatter?

    Raw XML from APIs or databases is often minified — all on one line with no whitespace. While efficient for machines, it's nearly impossible for humans to read and debug. Formatting adds structure that makes it easy to understand the hierarchy, spot errors, and work with the data.
