Ultimate XML Formatter
Professional XML tool with tree view, XPath testing, XML↔JSON conversion, and advanced formatting
The Ultimate XML Formatter is a professional-grade tool that goes far beyond basic XML formatting. It provides an interactive tree view where you can explore complex nested structures, see all attributes inline, and distinguish between elements, text nodes, comments, and CDATA sections with color-coded icons. The tree view lets you collapse and expand nodes to focus on specific parts of large documents, while hovering shows the full XPath for any element.
Advanced features include a live XPath query tester that lets you test expressions and see matching results instantly - perfect for learning XPath or debugging queries. The XML↔JSON converter handles bidirectional conversion with attribute preservation, making it easy to work with APIs that accept different formats. The attributes view displays all attributes in a sortable table with their XPath locations, ideal for auditing or finding specific attribute values across large documents.
The diff mode compares two XML documents and highlights every difference including added/removed elements, changed attributes, and modified content. Statistics show document structure at a glance - element count, attribute count, nesting depth, namespace count, and file size. Format with custom indentation, minify for production, and work with confidence knowing all processing happens locally in your browser for complete privacy. Whether you're debugging SOAP responses, working with SVG files, or managing configuration files, this tool provides everything you need.
