JSON to XML Converter

Q: How do I create XML attributes?

Prefix the key with the attribute prefix, by default `@_`: `{"@_id": "7"}` becomes `id="7"` on the parent element. Change the prefix if your JSON uses `@` or `$`.

Q: What happens to arrays?

`"tags": ["a","b"]` produces two ` ` elements. A top-level array is wrapped in the root element with one ` ` per entry (configurable).

Q: Can I omit the root wrapper?

Yes – clear **Root element**. The JSON must then be an object with exactly one key, which becomes the root.

Convert JSON to well-formed XML with a configurable root element, attributes via "@_" keys, repeated elements for arrays and optional XML declaration. Free.

What is JSON to XML?

Convert a JSON document into XML. Objects become nested elements, arrays become repeated elements with the same name, keys starting with the attribute prefix (default @_) become XML attributes and #text becomes element text.

How to use JSON to XML

Paste JSON into the JSON input box, or use Load sample or Open file.
Set Root element (clear it if your JSON already has a single top-level key), Array item element for top-level arrays and Attribute key prefix.
Choose Indentation and whether to Add XML declaration.
The XML output updates as you type; use Copy or Download.

Example

Input

{"@_id":"7","name":"Ada","tags":["a","b"]}

Output

<?xml version="1.0" encoding="UTF-8"?>
<root id="7">
  <name>Ada</name>
  <tags>a</tags>
  <tags>b</tags>
</root>

When to use JSON to XML

Use it to feed JSON data to XML-only systems such as SOAP services, RSS-like feeds or legacy integrations. XML has no native types, so numbers and booleans become plain text; if the receiving system expects a specific XSD, check element order and names against it.

How JSON to XML works

The JSON is parsed and every key is sanitized into a valid XML name (invalid characters become _, names starting with a digit get a leading _). The object is then serialized with fast-xml-parser's XMLBuilder: special characters are escaped (& → &), null values become empty elements (<note/>), an array value repeats the element once per item and a top-level array is wrapped as <root><item>…</item></root>.

Common Use Cases

Send JSON data to a SOAP or XML-RPC endpoint
Create XML test fixtures from JSON samples
Convert configuration exported as JSON into XML
Produce XML for tools that only import XML
