XML Beautifier

XML from build systems, SOAP responses and configuration generators usually arrives compressed into a single line — perfectly valid, completely unreadable. This beautifier re-indents the document: every element on its own line, nested elements one level deeper, so the hierarchy of your document is visible instead of implied.

Paste the XML and the formatted version appears instantly. You control the indentation — spaces or tabs, and how many — so the output matches your project's style, whether that is two-space web conventions or four-space enterprise settings files. Whitespace between tags is rebuilt; the text content of elements is preserved as-is.

Because the tool parses the document before printing it, it also catches structural errors: an unclosed tag, a misplaced attribute or an encoding problem shows up as a parse error with its position rather than as silently mangled output. That makes it a reasonable first stop whenever an XML file refuses to load — format it, and either it works or the error tells you where the problem is.

Two boundaries worth knowing. First, whitespace inside elements is treated as content, so documents that rely on significant internal whitespace should be spot-checked after formatting. Second, extremely large files are limited by browser memory. Everything runs locally in your browser and the document is never uploaded — exactly what you want when the XML contains endpoints, keys or internal hostnames.
