How it works

How to use the JSON to XML

  1. 01

    Paste JSON or load the sample. A single top-level key becomes the root element.

  2. 02

    Arrays repeat their parent tag. Keys starting with @ become attributes and #text becomes text content.

  3. 03

    Set a root or item name if you need one, then copy or download the XML.

About this tool

Why convert JSON to XML?

JSON is the default format for modern web APIs, but many systems still expect XML: SOAP services, RSS and Atom feeds, sitemaps, enterprise integrations, Android resources and legacy software. A JSON to XML converter translates the hierarchical structure of JSON into the tag-based structure of XML so the data can move between those systems.

This converter follows common conventions: arrays repeat their parent tag, keys that start with @ become attributes, a #text key becomes text content, and null becomes an empty element. Keys that aren't valid XML names are made safe automatically, and special characters are escaped.

  • Attributes and text

    Use @key for attributes and #text for element content.

  • Smart arrays

    Arrays repeat their parent element; top-level arrays use a configurable item name.

  • Valid output

    Element names are sanitised and &, <, > and quotes are escaped.

  • Formatting options

    2 or 4 space indentation, or compact output, with an optional XML declaration.

FAQ

Frequently asked questions

How are JSON arrays converted to XML?

Each item becomes an element named after the array's key. For example, {"tag": ["a", "b"]} becomes <tag>a</tag><tag>b</tag>.

How do I create XML attributes from JSON?

Prefix the key with @. For example, {"book": {"@id": "bk101", "title": "XML"}} becomes <book id="bk101"><title>XML</title></book>.

What happens to keys that aren't valid XML names?

Characters that aren't allowed are replaced with underscores, and names that start with a number get an underscore prefix, so the output is always well-formed.

Are my files uploaded anywhere?

No. This tool runs entirely in your browser using JavaScript. Your files and text never leave your device, so it's safe for private or confidential work.
