JSON to XML

Instant conversion

Paste any JSON object or array and get well-formed, indented XML output. Arrays are expanded as repeated elements. Null values become self-closing tags. Runs entirely in your browser — no data is sent to any server.

Conversion rules

JSON objects — Each key becomes an XML element. Nested objects create nested elements.
JSON arrays — Each array item becomes a repeated element with the same tag name as the parent key.
Null values — JSON null becomes a self-closing XML element: <tagName />.
Root element — The top-level JSON object is wrapped in a <root> element by default.
Special characters — Characters like <, >, &, " are escaped in the XML output.

Common use cases

Preparing data for payment APIs that accept XML format rather than JSON
Converting configuration objects to XML for legacy enterprise systems
Transforming data structures when integrating with ISO 20022 messaging workflows
Quick prototyping of XML payloads before building a full serializer

Dev snippet — JSON to XML (Node.js)

function jsonToXml(obj, indent = 0) {
  const pad = "  ".repeat(indent);
  return Object.entries(obj).map(([key, val]) => {
    if (val === null) return `${pad}<${key} />`;
    if (Array.isArray(val))
      return val.map(item => `${pad}<${key}>${jsonToXml(item, indent + 1)}${pad}</${key}>`).join("\n");
    if (typeof val === "object")
      return `${pad}<${key}>\n${jsonToXml(val, indent + 1)}${pad}</${key}>`;
    return `${pad}<${key}>${val}</${key}>`;
  }).join("\n");
}

const xml = `<?xml version="1.0" encoding="UTF-8"?>\n<root>\n${jsonToXml(yourObject, 1)}\n</root>`;
