XML Prettifier
About the XML Prettifier
The XML Prettifier enhances the readability of XML by formatting its content with proper indentation, line breaks, and structure — while leaving the underlying data completely unchanged.
Like JSON, XML is often transmitted without any whitespace to keep payloads small, which makes it unreadable to a human at a glance. This tool parses your XML using the browser's native XML parser, then re-serializes it with a newline before every opening tag, restoring the nested, indented structure so you can actually see how elements relate to one another — invaluable when you're debugging an API response, a config file, or a feed.
