What becomes the XML root element?

The tool wraps the entire JSON in a single root element. If your JSON object has one top-level key, that key becomes the root tag; otherwise a default root element is added.

How are JSON arrays converted?

Each array item becomes a repeating element with the same tag name as the parent key. For example, {"items": ["a", "b"]} becomes a b .

Are JSON attributes (keys starting with @) supported?

The tool uses a straightforward element-based conversion. Keys starting with @ are not treated as XML attributes; they become child elements. For attribute support, pre-process your JSON manually.

What use cases require converting JSON to XML?

SOAP web services, RSS/Atom feeds, legacy enterprise systems, XML-based config files (Maven POM, Spring), and any system that does not accept JSON.

Does this tool send my data to a server?

No. All conversion is performed entirely in the browser. Your data is never sent to any server.

How it works

■ What is JSON? JSON (JavaScript Object Notation) represents key-value pairs, arrays, and nested objects as text. Commonly used for API requests/responses and data exchange. ■ What is XML? XML (eXtensible Markup Language) is a markup language with tag-based structure. Widely used for SOAP, RSS, config files, and data exchange. ■ How conversion works JSON objects become XML elements; arrays become repeating elements. The output XML has a single root. All processing runs in the browser.
