About the XML to JSON Converter

XML (Extensible Markup Language) was the dominant data exchange format in the 2000s and is still widely used in enterprise systems, SOAP APIs, RSS/Atom feeds, and configuration files. JSON has largely replaced it for web APIs because it's more compact, easier to read, and natively parseable in JavaScript. This converter transforms XML documents into equivalent JSON objects, preserving the nested structure.

Tips for best results

  • XML attributes are represented as keys with an "@" prefix in the JSON output.
  • Deeply nested XML maps to deeply nested JSON — the hierarchy is preserved.
  • Large XML files close to the 10 MB limit may take a few extra seconds to process.

FAQs

XML elements become JSON object keys. Nested elements become nested objects. Element attributes are included as keys prefixed with "@". Text content of elements is represented as a "#text" key when the element also has attributes or children.

Basic XML is handled well. Complex namespace declarations may produce verbose key names in the JSON. For heavily namespace-dependent XML, post-processing the JSON may be needed.

Attributes are preserved in the JSON output as keys with an "@" prefix, so <person id="1"> would produce {"@id": "1"} alongside any child elements.

Yes. RSS and Atom feeds are XML documents. Upload the .xml feed file and convert it to JSON for use in JavaScript or other applications.

Yes. The output is valid, properly formatted JSON that can be parsed by any standard JSON library or JavaScript's JSON.parse().
