XML to JSON Converter — Convert XML to JSON Online

XML to JSON Converter parses XML markup and produces a JSON representation. Attributes are prefixed with @ and text content uses the #text key.

XML to JSON Mapping Rules

Converting XML to JSON requires decisions about how to represent XML-specific constructs that have no direct JSON equivalent. Attributes are represented as keys prefixed with @ (so the XML element <user id="42"> becomes {"@id":"42",...}). Text content of an element that also has attributes or child elements uses the key #text. An element with only text content becomes a simple string value. An element that repeats at the same level becomes a JSON array.

These conventions are widely used but not standardised — different libraries use different prefixes. SmartDevBox uses the common @/# convention from the fast-xml-parser library. If the consuming code expects a different convention, adjust the output accordingly.

Processing SOAP and RSS Feeds

SOAP API responses are the most common reason developers need XML-to-JSON conversion. A SOAP envelope wraps the actual response in layers of namespace-qualified XML: <soap:Envelope><soap:Body><GetUserResponse xmlns="..."><User><Id>42</Id></User></GetUserResponse></soap:Body></soap:Envelope>. Converting to JSON first, then using the JSONPath Evaluator to navigate to the data you need, is far easier than traversing the XML directly.

RSS and Atom feeds are XML documents listing article titles, links, and descriptions. Converting to JSON makes them easy to process in JavaScript: iterate the items array, extract the title and link fields, and display or store the results. The channel element in RSS becomes a JSON object with item as an array of article objects.

Common Use Cases

  • Converting SOAP API XML responses to JSON for JavaScript processing
  • Transforming XML configuration files to JSON
  • Parsing RSS or Atom feeds into JSON

Frequently Asked Questions

How are XML attributes represented in the JSON output?

Attributes are included as keys prefixed with @ (e.g. @id, @class). Text content is represented with the key #text.
