XML to JSON & JSON to XML Bi-Directional Converter

JSON and XML represent structured data using fundamentally different paradigms. JSON is based on key-value dictionaries and ordered lists with native primitive types (numbers, booleans, null, strings). XML is a hierarchical document markup tree where elements possess tag names, attributes, child elements, and mixed text content. Converting between them requires conventions for mapping attributes (e.g. @id="123"), element text (#text), and repeated sibling tags into native arrays.

In XML, repeated tags (such as multiple <item> tags inside <items>) indicate a collection. When converting to JSON, the converter detects sibling elements with identical tag names and aggregates them into a JavaScript Array ([]). Attributes are mapped using a configurable prefix (e.g. "@id" or "$id") to prevent naming collisions with child elements.

Many enterprise banking, ERP, and government APIs still return SOAP 1.1 / 1.2 XML responses wrapped in <soap:Envelope> and <soap:Body>. The converter includes an optional "Strip XML namespaces" filter, converting verbose tags like <soap:GetAccountResponse xmlns:soap="..."> into clean, idiomatic JSON objects for modern React and Node.js APIs.

XML characters such as &, <, >, ", and ' are strictly reserved. When generating XML from JSON, the serializer performs proper escaping or encapsulates raw markup in CDATA blocks (<![CDATA[ ... ]]>), ensuring generated files are 100% compliant with W3C XML specifications.

All conversions execute client-side using browser-native DOMParser and XMLSerializer APIs. No payload data, API tokens, or enterprise XML schemas ever leave your machine.
