If you’ve ever dealt with SOAP APIs, legacy data feeds, or RSS parsers, you know the struggle: XML is still everywhere, but your stack speaks JSON.
That’s exactly why I needed an API to convert XML to JSON — and why I ended up building one that’s free, fast, and incredibly easy to use.
Why Use an API to Convert XML to JSON?
XML used to be the standard for structured data. Today, most modern apps, APIs, and frontend frameworks rely on JSON. If you’re integrating with systems that still return XML, you need a clean way to convert that data to something your app can understand.
Here are some common use cases:
- Migrating from XML-based systems to REST APIs
- Parsing RSS feeds or SOAP responses
- Integrating government or legacy third-party data
- Converting vendor data feeds for internal use
Try It Now – Free XML to JSON API
This is a ready-to-use REST API that takes raw XML and returns clean JSON — no setup, no key required.
Endpoint:
POST https://node.nodetrigger.com/api/xml-to-json
Request Body:
Send raw XML inside a JSON object:
{
"xml": "<person><name>Jane</name><age>28</age></person>"
}
Response:
You’ll get structured JSON in return:
{
"json": {
"person": {
"name": "Jane",
"age": "28"
}
}
}
No need to parse or clean it yourself — the API handles everything behind the scenes.
Features
- Accepts standard, well-formed XML
- Converts XML to native JSON structure
- Returns clean, flattened output (no unnecessary arrays)
- Built-in error handling for malformed input
Why I Built This
I was working with a third-party data source that only returned XML — and I needed to pull it into a Vue frontend that expected JSON. Most libraries were either too bloated, required a backend, or didn’t handle nested structures well.
How to Use It (with CURL or Postman)
Example with CURL:
curl -X POST https://node.nodetrigger.com/api/xml-to-json \
-H "Content-Type: application/json" \
-d '{"xml":"<note><to>You</to><from>Me</from><body>Hello</body></note>"}'
Error Handling
If the XML is malformed or the request is missing data, you’ll get a simple error response:
{
"error": "Failed to parse XML",
"message": "Non-whitespace before first tag."
}
This makes it easy to debug and log XML issues in your app.
Frequently Asked Questions
Do I need to sign up or get an API key?
Yes. You just have to create your free account to get your API Key.
Can I convert large XML files?
Yes, but the API is optimized for lightweight to medium-sized XML documents. For very large XMLs, consider chunking or batch processing.
What happens with attributes?
Attributes are merged into the corresponding object for simplicity. If you need custom behavior, contact us.
