What happens if my JSON does not have a single root key?
XML requires a single root element, so our converter automatically wraps root-level JSON properties or arrays inside a `<root>...</root>` tag.
Convert JSON to XML Online
Transform JSON objects and arrays into clean, well-formed XML documents.
Instant JSON to XML Transformation
Powered by `fast-xml-parser`, our converter translates nested JSON keys into XML elements and maps `@_` prefixed properties directly into XML attributes.
How JSON Arrays and Objects Map to XML Tags
JSON objects become parent XML tags, primitive values become text nodes, and JSON arrays automatically repeat their parent tag name cleanly.
Enterprise Integration Use Cases
Ideal for bridging modern REST JSON payloads with legacy SOAP services, banking XML gateways, and ERP systems.
Frequently Asked Questions
How do I represent XML attributes in JSON?
Prefix any JSON key with `@_` (for example, `"@_id": "101"`) and the converter will output `<item id="101">`.
Is the generated XML validated?
Yes, the output is automatically formatted with an `<?xml version="1.0" encoding="UTF-8"?>` declaration and verified for well-formedness.
