When should I use JSON / XML conversion?
Use it when API response data, configuration files, integration documents, or test data need to be converted between JSON and XML formats.
What is the difference between JSON and XML?
JSON is commonly used in modern APIs and frontend development because it is compact and easy to parse. XML is often used in enterprise systems, legacy integrations, document exchange, and systems that require strict tag-based structures.
Why is a root tag required for JSON → XML conversion?
An XML document needs one top-level root element. JSON can start directly as an object or array, but XML requires a root tag to wrap the converted structure.
How are JSON arrays represented in XML?
JSON arrays are converted into repeated XML tags. You can set the array item tag name, such as item or option, to make the XML output easier to read.
How are XML attributes handled?
JSON does not have a native XML attribute concept, so XML attributes, namespaces, CDATA, and comments may be simplified during conversion. Review the result when working with complex XML.
What should I check when converting XML to JSON?
Repeated tags may become arrays, text values may be converted to numbers, booleans, or null, and complex XML-specific structures may be simplified. Always verify the converted JSON before using it in production.
Is my input data stored on the server?
This utility converts the input in the browser. During normal use, the JSON or XML data you enter is not stored on the server.
