JSON to XML Converter - Structured Data Converter
JSON to XML Converter
Instantly convert JSON objects into valid XML format. Customize your root elements and attributes with ease.
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard.
JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.
What is XML?
XML (Extensible Markup Language) is a markup language similar to HTML but without predefined tags. It allows you to define your own tags designed specifically for your data needs, making it highly flexible for representing complex, hierarchical data structures.
For decades, XML has been the industry standard for document processing and data interchange in enterprise environments, SOAP APIs, and configuration files, prioritizing structural integrity and validation.
Why convert JSON to XML?
While JSON has become the dominant format for modern web APIs, many legacy systems, enterprise applications, and SOAP-based services still strictly require XML.
Converting JSON to XML allows you to bridge the gap between modern front-end applications and older back-end systems. It is also essential for complying with certain industry standards that mandate XML for data interchange.

Frequently Asked Questions
Clear answers to common questions
Valid XML documents must have exactly one root element. Since JSON can be an array of objects (which would translate to multiple top-level XML elements), we wrap everything in a <root> tag to ensure validity.
Standard JSON doesn't distinguish between attributes and child elements. By default, all JSON keys become XML elements. Specialized key naming conventions (like @attribute) are needed for explicit attributes, which this basic converter may not support.
Yes, since processing is local, you can convert reasonably large files without uploading them to a server.
Currently, our tool uses 'root' as the default wrapper, but you can manually wrap your JSON in an object with your desired key before conversion.
Arrays in JSON are converted to repeated child elements in XML within their parent container.
