What is JSON to XML Converter?
The JSON to XML converter transforms data between JSON and XML formats in either direction. It handles nested objects, arrays, and XML attributes, preserving the data hierarchy and types where possible. The output is properly formatted with indentation. All processing happens in the browser.
How does JSON to XML Converter work?
This tool provides bidirectional conversion between JSON and XML. In JSON-to-XML mode, it recursively maps object keys to element names and values to text content. In XML-to-JSON mode, it parses the XML DOM and converts elements to objects, attributes to prefixed properties, and text content to string values.
Key Features

- Preserves XML attributes with configurable prefix
- Validates input before converting
- Pretty-printed output with indentation

Frequently Asked Questions
How are JSON arrays represented in XML?
JSON to XML converter turns JSON arrays into repeated XML elements. For example, an array of items becomes multiple <item> elements at the same level.
How are XML attributes handled in JSON?
XML attributes are converted to JSON properties with an @ prefix. For example, id='1' becomes '@id': '1'.
Is my data uploaded to a server?
No. All conversion happens in your browser using JavaScript. The data never leaves your device.
Can I convert both directions?
Yes. The tool supports both JSON-to-XML and XML-to-JSON conversion.
What if my input is invalid?
The tool validates the input before converting. If the JSON or XML is malformed, it shows an error message describing the problem.
