The XML Formatter transforms compact, single-line, or poorly formatted XML documents into beautifully structured, human-readable format with proper indentation and line breaks. XML (Extensible Markup Language) is widely used for configuration files, data interchange, web services (SOAP), RSS feeds, SVG graphics, and document formats like DOCX and XLSX. However, XML generated by applications or received from APIs is often minified or poorly formatted, making it extremely difficult to read and debug. Our formatter intelligently parses your XML document, identifies the hierarchical structure of elements, and applies consistent indentation that clearly shows parent-child relationships. Each element is placed on its own line (where appropriate), with child elements indented relative to their parents, making the document structure immediately apparent at a glance. The tool preserves all your data, including element attributes, text content, CDATA sections, and processing instructions, while only modifying whitespace for improved readability. All formatting happens entirely within your browser using the DOMParser and XMLSerializer APIs, ensuring your XML data remains private and never leaves your device. The formatter requires well-formed XML as input—if your XML has syntax errors, it will display an error message. You can use our XML Validator tool first if you're unsure about your XML's validity. Use this tool when debugging XML configurations, preparing XML for documentation, comparing XML documents, learning XML structure, or making API responses readable. The instant formatting dramatically improves productivity when working with XML data.
