XML Formatter & Validator

An XML formatter (XML beautifier) is a tool that takes raw or minified XML and reformats it with proper indentation, line breaks, and consistent structure. This makes XML much easier to read, debug and maintain.

This tool checks XML well-formedness: that every opening tag has a matching closing tag, attributes are properly quoted, there are no illegal characters, and the document has a single root element. It uses the browser's native DOMParser for accurate results.

Completely. All operations — formatting, validation, conversion — run entirely in your browser with JavaScript. Nothing is uploaded to any server. Your XML data stays on your device at all times.

XPath is a query language for selecting nodes from an XML document. Enter an XPath expression in the XPath field (e.g. //book or /catalog/book[@id='1']) and click Run to extract matching elements from your XML.

Yes! Click the "XML → JSON" button to convert your XML into a JSON representation. Attributes are mapped with "@" prefix, text content is captured, and nested elements are recursively converted to JSON objects or arrays.

Formatting (beautifying) adds indentation and line breaks to make XML human-readable. Minifying does the opposite — it removes all unnecessary whitespace to make the file as small as possible, ideal for transmission over networks or APIs.
