The Ultimate JSON to XML Converter Online
In the modern world of software development, data interchange is everything. While JSON (JavaScript Object Notation) has become the de facto standard for web APIs due to its lightweight nature and native JavaScript support, many enterprise systems, legacy architectures, and specialized tools still rely heavily on XML (eXtensible Markup Language). Our JSON to XML converter bridges this gap, providing a seamless, secure, and highly configurable way to transform your data.
🚀 Advanced Features
- Dynamic Root Mapping: Unlike basic converters, you can define exactly what the wrapping XML tag should be named.
- Advanced Array Handling: Choose between loose conversion or professional "Wrap Array" mode for strict schema compliance.
- Auto-Sanitization: We handle special characters like
&,<< /code>, and>automatically, ensuring your XML is always valid. - Local Browser Processing: Your data never leaves your machine. Privacy is baked into every conversion.
🛠️ Use Cases for Developers
- SOAP Integration: Rapidly generate XML payloads for legacy SOAP web services from modern JSON objects.
- Configuration Migration: Convert JSON app settings into XML config files for .NET or Java environments.
- Data Transformation (ETL): Clean and reshape JSON data into a structured hierarchy suitable for XML-based data warehouses.
- Legacy API Support: Connect your modern frontend (using JSON) to backend systems that only speak XML.

Frequently Asked Questions
Can I convert deeply nested JSON?
Yes. Our recursive parsing algorithm can handle JSON objects with infinite nesting levels, maintaining the correct hierarchy in the final XML output.
How are JSON numbers and booleans handled?
In XML, all data is represented as strings. Our converter takes your boolean (true/false) and numbers (123) and places them accurately as text content within the tags.
Is there a limit on file size?
Since the processing happens in your browser, the limit is governed by your computer's RAM. Usually, files up to several megabytes convert instantly.
