About JSON and XML Conversion
JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are both popular data interchange formats used in web development, APIs, and data storage. While JSON is more lightweight and easier to parse in JavaScript, XML provides better support for metadata, namespaces, and complex document structures.
Converting between JSON and XML is often necessary when working with legacy systems, SOAP APIs, modern REST APIs, or when migrating between different systems. This bidirectional converter automatically handles both directions while preserving the structure and data types of your data.
The converter intelligently handles arrays, nested objects, and primitive values in both directions. When converting to XML, it creates appropriate XML elements with type attributes where needed. When converting from XML, it reconstructs the original JSON structure. Invalid XML characters are automatically escaped, and tag names are sanitized to ensure valid output.
JSON/XML Converter FAQs
Is this JSON/XML converter safe to use?
Yes. The conversion runs entirely in your browser. Your data is never uploaded or stored on any server, ensuring complete privacy and security.
Does this tool save my data?
No. Once you refresh the page or close the tab, your input is cleared. Nothing is persisted or cached beyond your session.
Can I convert both JSON to XML and XML to JSON?
Yes! This is a bidirectional converter. Simply select your desired conversion mode from the dropdown menu - "JSON to XML" or "XML to JSON" - and the tool will adapt accordingly.
Can I convert complex nested structures?
Absolutely. The converter handles nested objects, arrays, and all data types in both directions, creating properly structured output with appropriate hierarchies.
How are JSON arrays converted to XML?
JSON arrays are converted to XML elements with a type="array" attribute. Each array item becomes a child element, maintaining the order and structure of your original data. When converting back from XML, arrays are reconstructed from these type attributes.
What happens to invalid XML characters?
Invalid XML characters (like <, >, &, ", ') are automatically escaped to their XML entity equivalents (e.g., <, >, &) when converting to XML, and properly unescaped when converting back to JSON.
Can I customize the root element name?
Yes, when converting JSON to XML. You can set a custom root element name before conversion. The tool will sanitize the name to ensure it's a valid XML tag name. This option is only available in JSON to XML mode.
What file formats are supported for upload?
You can upload `.json` files when in JSON to XML mode, and `.xml` files when in XML to JSON mode. The tool automatically validates the file type based on your selected conversion mode.
