Free JSON to XML Converter

XML (Extensible Markup Language) uses opening and closing tags to structure data hierarchically, while JSON uses key-value pairs with curly braces and square brackets. XML supports attributes on elements, namespaces, and mixed content (text alongside child elements), which JSON does not. JSON is more compact and easier for JavaScript to parse, while XML is widely used in enterprise systems, SOAP APIs, configuration files, and document formats like SVG and RSS.

XML is the better choice when you need document validation with XSD schemas, XSLT transformations, namespace support for mixing vocabularies, or when integrating with legacy enterprise systems and SOAP web services. XML is also required for specific formats like RSS feeds, Atom feeds, SVG graphics, and Android resource files. If you are building a REST API or a modern web application, JSON is usually preferred for its simplicity.

Each element in a JSON array is wrapped in an tag within the parent element. For example, a JSON array like {"colors": ["red", "blue"]} becomes redblue. Nested arrays and arrays of objects are handled recursively, preserving the full structure of your data.

Yes. The converter automatically escapes all XML-reserved characters: ampersands become &, less-than signs become <, greater-than signs become >, and double quotes become ". This ensures the output is valid, well-formed XML that any XML parser can read without errors.

Yes. By default, the converter wraps your JSON in a element, which is required because XML documents must have exactly one root element. You can type any valid XML element name into the root element field before converting. Valid names start with a letter or underscore and contain only letters, digits, hyphens, underscores, and periods.

No. All conversion happens entirely in your browser using JavaScript. Your JSON data never leaves your device and is never transmitted to any server. This makes the tool safe for converting sensitive or proprietary data structures.

The converter validates your JSON before attempting conversion. If the JSON contains syntax errors such as missing commas, unmatched brackets, or trailing commas, you will see a clear error message indicating what went wrong and the approximate position of the error. Fix the issue and try again.

Yes. The converter handles arbitrarily deep nesting of objects and arrays. Each nested object becomes a child element, and each nested array wraps its items in tags. The output XML is indented with two spaces per level so you can easily read and verify the structure at any depth.
