Convert JSON to XML online, free. JSON is the dominant data-interchange format for web APIs and config. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. JSON to XML conversion parses your JSON against the ECMA-404 / RFC 8259 grammar (https://www.rfc-editor.org/rfc/rfc8259), builds an in-memory model of its keys, nested objects and arrays, then re-serializes it as valid XML following the W3C XML 1.0 conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include SOAP web services, RSS/Atom feeds and legacy enterprise documents.
It maps the full structure of your JSON onto well-formed XML, following the W3C XML 1.0 conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste JSON and convert XML immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested JSON objects, tables and arrays are mapped faithfully onto XML.
Your JSON never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A JSON document and its XML equivalent:
JSON input:
{
"name": "Alice",
"age": 30,
"email": "[email protected]"
}Output:
<user>
<name>Alice</name>
<age>30</age>
<email>[email protected]</email>
</user>Paste your JSON into the editor and press "Convert to XML". The tool parses it against the ECMA-404 / RFC 8259 grammar, then re-serializes it as XML following W3C XML 1.0 conventions — instantly and entirely in your browser. You can validate or format the JSON first to be sure it is clean.
JSON already uses objects, arrays and typed scalars, so mapping to XML is close to one-to-one: objects become nested structures, arrays become lists, and numbers, booleans and null keep their types.
Numbers, booleans and null are preserved as native XML types wherever XML supports them, so standard documents convert losslessly and can be read back into the same structure.
JSON (JavaScript Object Notation) (JSON) — JSON is the dominant data-interchange format for web APIs and config. XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. This converter maps the structure of your JSON onto XML so you can use it for SOAP web services.
Yes. Invalid JSON is flagged with a clear error before anything is converted. Common JSON problems to check are matched braces and brackets, double-quoted keys, and no trailing commas. Starting from clean input keeps the generated XML accurate.
Yes. The entire JSON-to-XML conversion runs locally in your browser in JavaScript — your JSON is never uploaded, logged or stored. That matters when the data is something like REST/GraphQL API payloads, which should not leave your machine.
The generated XML is ready for SOAP web services, RSS/Atom feeds and legacy enterprise documents. Copy or download it and drop it straight into your tooling.
Converting JSON to XML manually can be a tedious and error-prone task. This tool offers a quick and reliable way to convert your JSON data into the widely-used XML format. Whether you're a developer integrating APIs or working with legacy systems, this tool simplifies the process, allowing you to focus on your core tasks while it handles the conversion for you.
The process is simple—just paste your JSON data into the input box, and the tool will generate the corresponding XML output instantly. The XML output is structured in a way that maintains the integrity of your original JSON data, with tags and attributes that closely reflect the original format.
JSON (JavaScript Object Notation) is widely used for data exchange in modern web applications, particularly when interacting with APIs or servers.
