JSON to XML Converter

Convert JSON to clean, indented XML — or parse XML back into JSON — with sensible handling of attributes, arrays and text.

Loading JSON to XML…

How it works

How to use the JSON to XML

Paste JSON
Or switch to XML → JSON and paste XML instead.
Set the root element
Choose the root tag name and indentation, and whether to include an XML declaration.
Copy or download
The output updates instantly; download it as a .xml or .json file.

Object keys become elements; invalid XML names are sanitized (e.g. first name → first_name).
Arrays become repeated elements with the same tag name.
Keys starting with @ become attributes, and #text becomes element text.
Special characters are escaped (&, <, ").
XML → JSON groups repeated child elements into arrays and can convert numeric and boolean text into JSON types.

FAQ

How are XML attributes represented in JSON?

As keys prefixed with "@", for example <book id="7"> becomes {"book": {"@id": 7}}. The same convention works in reverse.

Why did an element turn into an array?

When a tag repeats inside the same parent, its values are collected into an array, because JSON objects cannot contain duplicate keys.

Is my data uploaded anywhere?

No. This tool runs entirely in your browser. Your input never leaves your device, is not logged, and works offline once the page has loaded.
