Convert XML data into JSON format

XML to JSON Converter — Parse Legacy XML APIs Into Modern JSON Structures

XML was the dominant data interchange format from the late 1990s through the mid-2000s, and the systems built during that era — enterprise ERP platforms, banking mainframes, healthcare HL7 feeds, e-commerce EDI systems, government data APIs, and SOAP web services — still produce XML output that modern applications built around JSON must consume. The mismatch creates an integration layer that every XML-consuming application must implement: parse the XML, navigate the element hierarchy, extract values from text content and attributes, and restructure into the objects and arrays that the rest of the application expects. The XML-to-JSON converter eliminates this custom integration layer for one-off data transformations and provides the structural mapping configuration needed to automate it for recurring data feeds.

XML's structural concepts have no direct JSON equivalent, and the mapping conventions chosen during conversion determine whether the output JSON is idiomatic or awkward. XML attributes (@id, @type, @href) become properties in JSON — but the convention for representing them varies: some converters prefix attribute names with "@" to distinguish them from element names, others merge them into the element's property object without prefix, and others create a separate "_attributes" property. XML text content of an element that also has attributes must go somewhere in the JSON object — typically as a "#text" property or "value" property alongside the attribute properties. XML's element ordering is significant in some schemas but irrelevant in JSON objects. The converter exposes these mapping conventions as options with clear descriptions of the implications so the output JSON matches the conventions expected by the consuming application.

SOAP web service responses produce deeply nested XML that is particularly painful to work with manually. A SOAP response envelope wraps a body element that contains the actual response, which may be three or four levels of nesting before reaching any useful data. XPath expressions targeting specific values within a SOAP response are opaque to developers unfamiliar with the schema. Converting the SOAP XML response to JSON and then navigating the resulting structure with standard JavaScript dot notation or JSONPath is significantly more readable for most developers. The XML-to-JSON converter handles SOAP envelopes specifically, offering an option to strip the envelope wrapper and extract only the body content — reducing a deeply-nested SOAP response to a flat or minimally-nested JSON object containing just the response data.
