How it works

■ What is XML? XML (eXtensible Markup Language) is a markup language with tag-based structure. Widely used for SOAP, RSS, config files, and data exchange. ■ What is JSON? JSON (JavaScript Object Notation) represents key-value pairs, arrays, and nested objects as text. Commonly used for API requests/responses and data exchange. ■ How conversion works XML elements become JSON keys; same-named siblings become arrays; text becomes string values. All processing runs in the browser.

FAQ

Q: Why convert XML to JSON?
A: Modern APIs, JavaScript front-ends, and NoSQL databases work natively with JSON. Converting legacy SOAP, RSS, or XML config responses to JSON lets you process them with standard JS/Python/PHP tooling without an XML parser.
Q: How are XML attributes handled in JSON output?
A: By default, element attributes are merged into the JSON object alongside child elements. The exact behaviour depends on the converter, but common conventions include prefixing attribute keys with @ or flattening them as sibling keys.
Q: What happens when sibling elements have the same tag name?
A: Repeated sibling elements with the same name are automatically grouped into a JSON array. For example, two <item> elements become "item": ["a", "b"].
Q: Are XML namespaces preserved?
A: Namespace prefixes (e.g. ns:element) are kept as-is in the JSON key names. Namespace declarations (xmlns) may be included as attributes depending on the conversion setting.
Q: Does this tool send my data to a server?
A: No. All conversion is performed entirely in the browser. Your data is never sent to any server.
