JSON to XML
Convert JSON data to well-formatted XML. Handles nested objects, arrays, and special characters.
About JSON to XML Conversion
Converting JSON to XML is a common requirement when integrating modern REST APIs with legacy SOAP-based systems, generating XML configuration files from JSON data sources, or preparing data for enterprise middleware platforms. JSON to XML conversion bridges the gap between modern web APIs and enterprise systems that still rely on XML as their primary data format. This converter handles nested objects, arrays, null values, and special characters with proper XML escaping.
JSON vs XML Comparison
JSON and XML serve similar purposes but differ significantly in design. JSON uses key-value pairs with curly braces and brackets, making it compact and native to JavaScript. XML uses hierarchical tags with optional attributes, namespaces, and schema validation (XSD). JSON files are typically 30-50% smaller than equivalent XML documents. However, XML supports mixed content (text with embedded tags), processing instructions, and CDATA sections that have no direct JSON equivalent.
When converting JSON arrays to XML, each array item is typically wrapped in a repeated element tag. JSON null values become empty self-closing tags. Boolean and numeric values are converted to text content. Key names that contain special characters are sanitized to comply with XML naming rules -- only letters, digits, hyphens, underscores, and periods are allowed in XML element names, and names cannot start with a digit.
