Transform JSON data into structured XML with built-in syntax validation. Upload .json files or paste content directly into the converter to generate clean XML output. The tool maps JSON objects to XML elements using keys as tag names, wraps array entries in individual tags, and automatically escapes special characters. Once converted, you can download the result as an .xml file or copy it to your clipboard.
Easily translate JSON data into a properly structured XML format.
To start, paste your JSON into the input area or drag a .json file directly into the browser. The tool validates the JSON syntax before beginning the conversion. If the JSON is malformed, an error message will pinpoint what needs to be fixed. Once the code is valid, click "Convert to XML" to generate the output.
JSON objects are converted into XML elements, with object keys serving as the tag names. For arrays, each entry is wrapped in an <item> element to maintain a valid XML structure. String values become the text content of elements, while numbers, booleans, and null values are converted into their string equivalents. The converter preserves the original hierarchy by nesting XML elements exactly as they appear in the JSON.
To ensure the resulting XML is valid and ready for use in other applications, the converter automatically escapes reserved characters. This includes converting ampersands (&), less-than signs (<), greater-than signs (>), and quotes (") into their respective XML entities. This prevents parsing errors in your target system.
XML tag names have stricter requirements than JSON keys; for example, they cannot contain spaces or start with certain characters. To prevent invalid output, this tool sanitizes keys by replacing invalid characters with underscores. Additionally, empty arrays will generate empty parent elements, and null values are represented as self-closing tags.
