Can all JSON be converted to XML?

Most JSON can be converted to XML, but some constructs need special handling. JSON arrays produce repeated XML elements with the same tag name. JSON keys that start with numbers or contain special characters may need sanitizing, as XML element names have stricter rules.

Can all XML be converted to JSON?

XML features that have no JSON equivalent — like XML attributes, processing instructions, and mixed content (text and elements in the same node) — require conventions to represent in JSON. The tool uses common conventions like `@attr` for attributes and `#text` for text nodes.

What is a common use case for JSON to XML conversion?

Sending data from a REST API to a SOAP or XML-based legacy system is a common scenario. Another is generating XML configuration files (like Android layouts or Maven POMs) from structured data.

Does this tool validate the XML output?

The tool produces well-formed XML, but it does not validate against a DTD or XML Schema. If you need schema-valid XML, you will need to post-process the output to match your target schema.

About JSON ↔ XML

This tool converts between JSON and XML in both directions. XML is still widely used in enterprise systems, SOAP APIs, configuration files (Maven, Spring, Android), and document formats. Converting between the two formats is a common task when integrating modern REST APIs with legacy systems or vice versa.

✓Bidirectional conversion — JSON to XML and XML to JSON
✓Produces well-formed, properly indented XML output
✓Handles JSON arrays by repeating XML elements
✓Preserves attribute and text node semantics when converting XML to JSON
