Common Use Cases
- Converting SOAP responses for REST clients
- Importing XML data into JavaScript applications
- Migrating legacy XML feeds to JSON APIs
XML served the web for decades, but modern apps and APIs run on JSON. If you have SOAP responses, RSS feeds, configuration files, or data exports in XML, converting to JSON makes them instantly usable in JavaScript, Python, Ruby, Go, and every language with native JSON parsing. This tool handles the mapping so you do not have to write XSLT or custom parsers.
XML uses tags, attributes, and mixed content in a verbose tree structure. JSON uses lightweight key-value pairs and arrays that parse directly into native objects in most programming languages.
Why Convert XML to JSON?
Use XML data in JavaScript and Python
Both JavaScript (JSON.parse) and Python (json.loads) can parse JSON into native objects with one line of code. No XML parser libraries, no DOM traversal, no XPath queries needed.
Modernize SOAP and legacy feeds
If you are consuming SOAP services, RSS feeds, or legacy XML APIs, converting to JSON lets you integrate that data into modern REST-based architectures and frontend frameworks.
Smaller payloads over the wire
JSON is typically 30-50% smaller than equivalent XML because it has no closing tags, no attributes syntax, and no namespace declarations. Smaller payloads mean faster API responses.
Direct integration with NoSQL databases
MongoDB, CouchDB, Firebase, and other document databases store JSON natively. Converting XML to JSON lets you import data directly without an intermediate transformation layer.
When to use each
Use XML when...
- Working with SOAP services and enterprise APIs
- You need schema validation with XSD
- Documents have mixed content and attributes
- XSLT transformations are part of your pipeline
- Regulatory requirements mandate XML
Use JSON when...
- Building REST APIs and modern web apps
- You want lightweight, fast parsing
- Data is structured as key-value pairs
- The consumer is JavaScript, Python, or Go
- Storing data in MongoDB or Firebase
Common use cases

- Migrating legacy XML feeds to JSON APIs
How to use
- Upload your XML file. Drag and drop a .xml file onto the upload area, or click to browse. Files up to 500 MB are supported.
- Start the conversion. Click Convert File. XML elements are mapped to JSON keys, repeating elements become arrays, and the full hierarchy is preserved as nested objects.
- Download your JSON. Save the .json file and use it in your JavaScript app, Python script, REST API, or NoSQL database. Files are deleted from our servers within 1 hour.
Frequently asked questions
- How are XML attributes handled?
- Attributes are mapped to JSON keys using a conventional prefix so they can be distinguished from child elements in the output.
- What happens to repeating XML elements?
- Repeating sibling elements with the same name are grouped into a JSON array automatically.
- Are XML namespaces preserved?
- Namespace prefixes are included in the JSON key names so you can identify which namespace each element belongs to.
- Can I convert SOAP responses?
- Yes. SOAP envelopes are standard XML. Upload the response and the entire structure, including headers and body, is converted to JSON.
- Does it handle CDATA sections?
- Yes. CDATA content is extracted as plain string values in the JSON output.
- Is converting XML to JSON free?
- Yes. Free with no signup. Anonymous users get a daily allowance, registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
- What is the file size limit?
- The maximum file size is 500 MB per conversion.
