Format and validate XML documents. This tool is designed to provide a seamless experience for developers by handling complex operations directly in the browser.
XML (eXtensible Markup Language) is a foundational data format used for everything from web services (SOAP) to configuration files (web.config, pom.xml). However, XML can quickly become unreadable when it's minified or deeply nested. Our XML Formatter/Validator is a professional-grade utility designed to restore structure and clarity to your XML data. It parses the input and applies a clean, hierarchical layout with customizable indentation. Beyond simple formatting, it serves as a robust validator. It checks for "well-formedness," ensuring that every opening tag has a corresponding closing tag, attributes are properly quoted, and the overall structure adheres to the XML specification. This dual functionality makes it an essential tool for anyone working with legacy systems, enterprise integrations, or complex configuration management.
Paste your raw, minified, or unformatted XML into the editor. Click "Format" to apply consistent indentation and line breaks. The tool will also validate your XML structure against standard rules, highlighting any syntax errors or unclosed tags.
In an enterprise environment, XML is often the language of data exchange. Debugging a 10MB XML log file or a complex SOAP response is nearly impossible without proper formatting. Our tool provides instant visual feedback, allowing you to quickly navigate through elements and attributes. The validation feature is particularly critical; it saves hours of troubleshooting by pinpointing exact line numbers where an XML structure is broken. Whether you're a Java developer managing Maven dependencies or a system administrator configuring IIS, this tool streamlines your workflow. Most importantly, it operates entirely client-side. Your sensitive configuration data, proprietary schemas, and business logic never leave your browser, providing a level of security that server-side formatters simply cannot match.
Mismatched Tags: An opening tag does not have a corresponding closing tag.
Fix: Ensure every <tag> has a matching </tag> and that they are properly nested.
Invalid Attributes: Attributes are missing quotes or have illegal characters.
Fix: Wrap all attribute values in double quotes (e.g., id="1").
Multiple Root Elements: XML must have exactly one root element.
Fix: Wrap all top-level elements in a single parent container.
