Convert XML to JSON online: tool and guide
Transform your XML data into structured JSON for your modern web applications and APIs. Free online tool.
Published on January 15, 2026Many legacy APIs, RSS feeds, SAP exports and SOAP services return their data in XML. Modern applications prefer JSON. An online XML-JSON converter allows you to bridge this gap immediately.
Understanding the conversion
XML to JSON conversion transforms tags into object keys and their content into values. XML attributes are generally prefixed with @ to distinguish them from child elements. Repeated elements with the same name are grouped into a JSON array. The difficulty lies in handling ambiguous cases: a single element can become an object or an array depending on the context.
📊 Conversion table
| XML (input) | JSON (output) |
|---|---|
| <name>Alice</name> | {"name": "Alice"} |
| <user id="1"><name>Alice</name></user> | {"user": {"@id": "1", "name": "Alice"}} |
| <items><item>a</item><item>b</item></items> | {"items": {"item": ["a", "b"]}} |
💡 Practical examples
Copy the XML body of the SOAP response, convert to JSON and manipulate the data with standard JavaScript methods (map, filter, reduce).
RSS feeds are in XML. Convert them to JSON to easily display them in a React or Vue application without a specialized parsing library.
SAP often exports in XML IDOC format. Convert to JSON, normalize the structure and import into your relational database or MongoDB.
