Free XML Formatter / Pretty Printer
Turn minified or messy XML into a readable, indented document in one click. The formatter walks the markup without an external parser: it indents elements by nesting depth, keeps <!-- comments -->, <![CDATA[...]]> blocks, and <?processing instructions?> intact, and normalizes whitespace inside text nodes. Ideal for configs, feed parsing, and API responses.
Why beautify XML?
Minified XML from APIs, exports, or legacy systems is painful to read and diff. Pretty-printing makes structure visible at a glance — parent/child hierarchy, attribute placement, and text content — which speeds up debugging, documentation, and code review. It never changes the meaning: whitespace is insignificant to XML semantics except inside CDATA and pre-like content, which are preserved verbatim.
XML Formatter FAQ
Does it validate my XML? It formats well-formed input and reports balanced-tag errors; it is not a full schema validator. Is whitespace inside tags changed? Only inter-tag whitespace is normalized — attribute spacing is preserved as written. Is my data sent anywhere? No — formatting runs locally in your browser.
