XML Formatter & Validator
Format XML with proper indentation and validate that it is well-formed.
Format XML with proper indentation and validate that it is well-formed.
Paste your XML into the input area and click "Format XML" to beautify it with consistent indentation, or "Validate" to check whether the document is well-formed. The formatter uses the browser's built-in DOMParser to parse the XML and then reconstructs it with clean 2-space indentation. Validation errors are displayed with clear messages.
XML documents from APIs, configuration files, and data feeds are often delivered as a single line or with inconsistent formatting. Properly indented XML reveals the document hierarchy, makes it easy to locate specific elements, and helps identify structural issues. Whether you are working with SOAP responses, Maven POM files, or SVG graphics, formatted XML saves significant debugging time.
The validator checks that your XML is well-formed according to the XML specification. It catches common issues including unclosed tags, mismatched tag names, invalid characters, and missing root elements. Fix these problems before processing XML in your application to avoid runtime errors.
All parsing and formatting happens in your browser using the native DOMParser API. Your XML data is never sent to any server, ensuring complete privacy for sensitive configuration files and data.
