Convert your JSON files into XML format. Our free online tool makes it easy to transform your structured JSON data into standardized XML format for system integration, data exchange, and more. No Signup Required.
Converting your JSON data to XML format is simple and straightforward:
The conversion process transforms your JSON data into a structured XML format, preserving the hierarchical nature of your data. This makes it compatible with XML-based systems and standards while maintaining the semantic structure of your original JSON data.
JSON was never intended to become a universal data format. Douglas Crockford, who formalized JSON in the early 2000s, initially created it as a simple way to transmit data between server and browser in JavaScript applications.
What's remarkable is that JSON wasn't introduced through formal standardization—it spread organically as developers recognized its elegance and simplicity.
The format gained such momentum that it effectively dethroned XML, which had been the dominant data interchange format for years despite being significantly more verbose and complex.
Perhaps most surprisingly, JSON's syntax was actually a subset of JavaScript that Crockford identified as being language-independent.
This accidental universality helped JSON become the backbone of modern APIs and web services, with an estimated 95% of public APIs now using JSON as their primary data format—a testament to how an elegant, minimalist solution can sometimes outperform more elaborate, formally designed alternatives.
When converting JSON to XML, a fascinating technical process takes place to transform structured data between two different hierarchical formats.
JSON is inherently hierarchical and can represent complex nested structures with variable depths, while XML provides a similar hierarchical model but with different syntax and conventions.
The conversion engine must implement thoughtful mapping algorithms that make decisions about how to represent JSON objects and arrays as XML elements and attributes.
For JSON objects, the process typically involves creating XML elements with nested structure, with careful attention to proper namespace management and element naming.
For JSON arrays, the conversion often requires creating repeated element structures with consistent patterns while preserving the original data relationships.
One of the key challenges is handling JSON's simpler type system and mapping it to XML's more complex model with attributes, elements, and mixed content.
Modern JSON-to-XML converters employ sophisticated transformation rules that preserve semantic meaning while adapting to the different structural paradigms of each format.

</users>Our JSON to XML converter allows you to transform JSON (JavaScript Object Notation) files into XML format. Simply upload your JSON file, configure any parsing options if needed, and download the generated XML file.
You can customize the structure of the XML output, choose whether to include headers, and specify how to handle nested JSON objects and arrays. These options help ensure the XML output meets your specific requirements.
Yes, our tool provides a preview of the converted XML data before you download it. This allows you to verify that the conversion meets your expectations and make any necessary adjustments to the parsing options.
Yes, you can upload JSON files up to 10MB in size. For larger files, we recommend splitting them into smaller chunks or using a desktop application.
Most conversions are completed within seconds. The exact time depends on the file size, complexity of the JSON structure, and your device's processing power, since all processing happens directly in your browser.
Yes, we take data security seriously. This tool processes your files entirely in your browser - your JSON files are never uploaded to our servers. This means your data never leaves your device, ensuring complete privacy and security.
Converting JSON to XML is useful for many purposes: integrating with legacy systems that require XML, working with SOAP web services, creating standardized data exchange formats, or preparing data for applications that specifically require XML format.
While this tool specifically converts from JSON to XML, we also offer other converters in our toolbox that allow you to work with different data formats, including XML to JSON conversion.
No, we don't store any of your files. Since the conversion happens entirely in your browser, your JSON data never reaches our servers. Once you close the browser tab or navigate away, all processed data is automatically cleared from your browser's memory.
