Frequently asked questions

How do I convert JSON to XML?

Paste your JSON into JSON input or click Load sample. Each key becomes an element and its value becomes the element content, indented with 2 spaces in XML output. Copy the result with the copy button.

How do I add XML attributes?

Add a key named _attributes whose value is an object of attribute names and values. For example, giving person an _attributes object with id set to "1" outputs a person element with id="1". Load sample shows a working example.

How do I get a single root element?

Every top-level key becomes a top-level element, so JSON with several top-level keys gives several root elements. Wrap your data in one key, such as root, to get well-formed XML with a single root.

How are JSON arrays converted?

An array repeats its element: a key named item holding three values produces three item elements. A top-level array is not supported, so wrap it in an object key first.

Can I add an XML declaration?

Yes. Add a _declaration key at the top level with an _attributes object holding version "1.0" and encoding "utf-8", and the output starts with the matching xml declaration line. Without it, no declaration is added.
