About XML to JSON

Convert XML to JSON format. Part of the DevTools Surf developer suite. Browse more tools in the Converters collection.

Use Cases

• Frontend devs converting XML API responses to JSON for JavaScript consumption
• Mobile developers transforming XML feeds into JSON for app data layers
• Backend devs migrating SOAP services to JSON-based REST APIs
• Data engineers converting XML data exports to JSON for modern pipelines

Tips

• Check how XML attributes are represented in the JSON output
• Verify that repeated XML elements become JSON arrays
• Review the handling of XML mixed content and text nodes

Fun Facts

• There is no single standard for XML-to-JSON conversion; at least 5 different conventions exist, including BadgerFish and Parker.
• XML attributes have no natural JSON equivalent, so converters typically prefix them with '@' or create nested objects.
• The shift from XML to JSON APIs accelerated in 2006 when major services like Twitter and Flickr added JSON endpoints.

FAQ

How are attributes handled?

Prefixed with `@` in the output: `<row id="1">` becomes `{"@id": "1"}`. Toggleable — other conventions (underscore prefix, attributes object) are also available.

What about text content alongside children?

Mixed content gets a `#text` key. `<p>hello <b>world</b></p>` → `{"#text": "hello ", "b": "world"}`.

Are namespaces preserved?

Yes — element names include their prefix (`ns:tag` stays as `ns:tag` in JSON). Toggle off to strip prefixes if your consumer doesn't care about namespaces.

What about numeric values?

All XML values are strings by default. Toggle 'infer types' to parse numbers and booleans — useful when you control both ends of the pipeline.
