Frequently Asked Questions
XML attributes are converted to JSON keys prefixed with "@". For example, <book id="1" lang="en"> becomes {"@id": "1", "@lang": "en", ...}. Text content of an element becomes "#text". This convention follows the BadgerFish/Parker conventions used by most XML-to-JSON tools.
If the same tag appears multiple times under the same parent, they are grouped into a JSON array. For example, multiple <item> tags become "item": [...]. Single occurrences remain as objects. This is the standard behavior and mirrors how most XML parsers work.
XML documents must have exactly one root element, but JSON objects can have multiple top-level keys. When converting JSON to XML, all keys are wrapped inside a root element (default: <root>). You can customize the root element name in the options above.
No. All conversion happens entirely in your browser using JavaScript. Your XML and JSON data never leaves your computer. This tool works completely offline after the page loads, making it safe for sensitive or confidential data.
XML (eXtensible Markup Language) is verbose, supports attributes and comments, and is preferred in enterprise/legacy systems (SOAP, RSS, SVG). JSON (JavaScript Object Notation) is compact, easier to parse in JavaScript, and is the standard for modern REST APIs. XML supports namespaces and schemas (DTD/XSD); JSON has JSON Schema. For new projects, JSON is usually preferred unless interoperability with XML-only systems is required.
