XML to JSON Converter
Parse XML documents and convert them to clean JSON. Maps XML elements to JSON keys, handles nested elements as objects, and converts repeated elements to arrays.
Parses well-formed XML and produces equivalent JSON structure.
Maps repeated XML elements to JSON arrays automatically.
Handles nested element hierarchies as nested JSON objects.
Converts XML text content to JSON string values.
Useful for consuming XML API responses in JSON-native environments.

XML attributes are commonly mapped to keys prefixed with @ in JSON — check how your target system expects them to be represented.
All XML text values are converted as strings; if you need typed numbers or booleans, post-process the JSON with a schema transformation.
Mixed content (elements containing both text and child elements) can produce complex nested structures — review the output carefully.
Normalize single-element fields to arrays explicitly in your code after conversion to handle the single-vs-multiple-element ambiguity.
Strip XML namespaces before conversion if they are not relevant to the consuming application, to keep JSON keys clean.
For production XML-to-JSON pipelines, use a server-side library with configurable mapping options rather than relying on a fixed online converter.

Understanding XML to JSON Converter
XML has been the backbone of enterprise data exchange for more than two decades. Web services built on SOAP, RSS and Atom syndication feeds, SVG graphics, Microsoft Office document formats, Android manifest files, Maven build configurations, and countless proprietary data exports all rely on XML. Despite the rise of JSON as the default format for REST APIs and modern web applications, development teams regularly encounter XML data from legacy systems, third-party integrations, or industry-standard protocols. Converting XML to JSON is one of the most common format transformation tasks in full-stack development and data engineering, and it requires careful handling of the structural differences between the two formats.
The fundamental challenge in XML-to-JSON conversion is that XML supports constructs with no direct JSON equivalent. XML attributes are metadata attached to elements rather than child data nodes. XML allows mixed content where an element contains both text and child elements simultaneously. XML namespaces add URI-qualified prefixes to element and attribute names. XML supports processing instructions, comments, and CDATA sections. JSON's simpler model of nested objects and arrays must absorb all of this richness through conventions. The most widely adopted convention maps attributes to keys prefixed with '@', wraps text content in a '#text' key when mixed with child elements, and collapses repeated sibling elements into arrays.
The practical impact of the repeated-element-to-array mapping is significant for API integration work. A well-designed XML document might use a single child element or multiple repeated elements under the same parent depending on the data — for instance, a user with one address produces a single <address> element, while a user with three addresses produces three <address> elements. This polymorphism means the JSON shape changes depending on the data, which complicates client code that expects a stable schema. Developers consuming converted XML-to-JSON data should always normalize arrays explicitly in their application code to handle the single-element edge case.
This XML to JSON converter accepts any well-formed XML document and produces clean, indented JSON. It handles nested element hierarchies, repeated elements, attributes, and self-closing tags. The converter validates that the input is well-formed XML before processing — malformed XML (unclosed tags, mismatched brackets, invalid characters) produces a descriptive error. The output JSON is immediately usable in JavaScript, Python, Node.js, and any language with a standard JSON parser. For lightweight integration tasks, scripting, and data exploration, this tool eliminates the need for a local XML parsing library and provides a visual inspection of the converted structure.
