About JSON to XML Converter
The JSON to XML converter transforms JSON documents to XML using fast-xml-parser — a high-performance, zero-dependency parser that handles the full spectrum of JSON nesting. JSON objects become XML elements, arrays become repeated sibling elements, and primitive values become text content. Both editors are live: edit one side and the other updates instantly. Swap to XML→JSON to reverse the direction at any point.

Frequently Asked Questions
QHow are JSON arrays handled?
JSON array items are expanded as repeated XML sibling elements with the array's key as the element name. For example, `{"items": [1, 2]}` becomes `<items>1</items><items>2</items>`.
QCan I add XML attributes?
The converter produces element-based XML from JSON keys. To produce XML attributes, restructure your JSON to use the fast-xml-parser attribute prefix convention or edit the XML output directly.
QIs my data sent to a server?
No. All conversion runs in a Web Worker inside your browser. Nothing is transmitted to any server.
