XML ↔ JSON

Bridging Two Formats That Don't Naturally Speak to Each Other

XML and JSON both represent structured data — but in very different ways. Modern APIs default to JSON. Enterprise systems, legacy services, SOAP endpoints, and configuration files still use XML. When you need to work with both, converting between them manually is tedious and error-prone.

This tool converts XML to JSON and JSON to XML in your browser. Paste in one side, get the other side. Nothing is uploaded to any server.

Before and After

XML input:

<user>
  <id>1042</id>
  <name>Priya Sharma</name>
  <email>priya@example.com</email>
  <roles>
    <role>admin</role>
    <role>editor</role>
  </roles>
  <active>true</active>
</user>

JSON output:

{
  "user": {
    "id": "1042",
    "name": "Priya Sharma",
    "email": "priya@example.com",
    "roles": {
      "role": ["admin", "editor"]
    },
    "active": "true"
  }
}

How the Conversion Works

XML→JSON: An XML DOM parser reads the element tree. Each XML element becomes a JSON key. Text content becomes a string value. Multiple sibling elements with the same tag become a JSON array. Attributes can be mapped to prefixed keys (e.g., @id). The result is a JSON object mirroring the XML hierarchy.

JSON→XML: Each JSON key becomes an XML element tag. Nested objects produce nested elements. Arrays produce repeated elements with the same tag name. Primitive values become element text content.

Key conversion rules:

Where You Need This

Integrating with SOAP or legacy APIs: Older enterprise services output SOAP/XML responses. Converting to JSON lets you work with this data in modern JavaScript, Python, or Node.js environments without parsing XML manually.

Data migration: Moving data between systems — a CSV→XML export from an old system needs to become JSON for the new API. Convert incrementally or as a batch.

Config file formats: Some tools use XML configuration (Maven pom.xml, Spring XML config). Converting them to JSON for comparison or documentation purposes is faster with a converter than manual transcription.
