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

  • Bidirectional conversion: JSON to XML and XML to JSON
  • Handles nested objects and arrays
  • Preserves XML attributes with configurable prefix
  • Validates input before converting
  • Pretty-printed output with indentation
  • Copy output to clipboard
  • Download as .xml or .json file
  • Maps JSON keys to XML elements and attributes in both directions
