How do I convert JSON to XML?

Paste your JSON into the converter on this page and pick XML as the output. Conversion happens instantly in your browser — nothing is uploaded. You can also call the free API: POST /api/v1/convert with { from: "json", to: "xml", data }.

Is the JSON to XML converter free?

Yes. The on-page JSON-to-XML converter is free and runs locally in your browser. The developer API is also free during beta, with a per-call paid tier for bulk and large payloads.

Convert JSON to XML

Paste your JavaScript Object Notation (JSON) and convert it to Extensible Markup Language (XML) in one click. Runs entirely in your browser — no upload, no signup.

Input (JSON)

[
  { "id": 1, "name": "Ada Lovelace", "role": "Engineer", "active": true },
  { "id": 2, "name": "Alan Turing", "role": "Researcher", "active": false }
]

Output (XML)

Convert this via the API (curl)

curl -X POST "https://data.wrapper-agency.com/api/v1/convert" \
  -H "Content-Type: application/json" \
  -d '{"from":"json","to":"xml","data":"[\n  { \"id\": 1, \"name\": \"Ada Lovelace\", \"role\": \"Engineer\", \"active\": true },\n  { \"id\": 2, \"name\": \"Alan Turing\", \"role\": \"Researcher\", \"active\": false }\n]"}'

Free conversion API — no key during beta. POST { from, to, data }, get back the converted string. All conversion runs server-side; nothing is stored.

JSON vs XML

JSON

A lightweight, human-readable data-interchange format. The default for web APIs and config.

XML

A verbose, tag-based markup format common in enterprise systems, SOAP, RSS, and legacy feeds.

How to convert JSON to XML

FormatForge parses your JSON into an in-memory data structure, then serializes it as XML. Numbers, booleans, and null values are preserved, and nested structures are mapped to XML's native shape.

Example

JSON in

[
  { "id": 1, "name": "Ada Lovelace", "role": "Engineer", "active": true },
  { "id": 2, "name": "Alan Turing", "role": "Researcher", "active": false }
]

XML out

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <item>
    <id>1</id>
    <name>Ada Lovelace</name>
    <role>Engineer</role>
    <active>true</active>
  </item>
  <item>
    <id>2</id>
    <name>Alan Turing</name>
    <role>Researcher</role>
    <active>false</active>
  </item>
</root>

Convert JSON to XML in code

Send the conversion to the free API and get the result back as a string:

curl -X POST "https://data.wrapper-agency.com/api/v1/convert" \
  -H "Content-Type: application/json" \
  -d '{"from":"json","to":"xml","data":"...your JSON as a string..."}'

FAQ

Does converting JSON to XML change my data?: No — the conversion is structural. Your values are preserved; only the serialization format changes.
Is my data uploaded anywhere?: The on-page converter runs locally in your browser. The API processes your payload server-side and stores nothing.
