JSON to XML Converter

A JSON to XML converter is an online tool that transforms JSON (JavaScript Object Notation) data into XML (eXtensible Markup Language) format instantly. Whether you're a developer integrating with legacy XML systems, a data engineer preparing data for XML-based workflows, or a system administrator working with SOAP APIs, our converter produces well-formed XML with customizable structure from JSON data.

This tool supports customizable root elements, proper attribute handling, nested object transformation, and array element naming. Simply paste your JSON data, configure XML output options, and get properly formatted XML ready for SOAP services, RSS feeds, or any XML-based system. The conversion is performed client-side, ensuring your data remains private and secure.

While JSON has become the dominant format for modern web APIs, many enterprise systems, legacy applications, and industry standards still rely on XML. Converting from JSON to XML is essential when integrating modern REST APIs with traditional SOAP services, preparing data for XML-based document systems, or adapting data for industries like healthcare (HL7) and finance that mandate XML formats.

Backend developers use JSON to XML converters to transform API responses for legacy system integration, prepare data for SOAP web services, and convert configuration data for XML-based tools. Enterprise architects benefit from bridging modern microservices (JSON) with traditional enterprise service buses (XML), while data engineers use converters to prepare data for ETL pipelines that require XML input.

The tool saves time by automating the conversion process, handles complex nested structures correctly, and ensures well-formed XML output that passes validation. It's particularly valuable when working with large datasets, integrating multiple systems with different format requirements, or migrating data from modern JSON APIs to legacy XML systems.

SOAP API Integration: Convert JSON API responses to XML for SOAP web service requests and legacy system integration.

Enterprise System Integration: Transform modern REST API data to XML for enterprise service bus and legacy middleware.

Data Format Migration: Convert JSON configuration or data files to XML for systems requiring XML format.

RSS/Atom Feeds: Generate XML feed structures from JSON content management system data.

Industry Standards: Prepare data in XML format for healthcare (HL7), finance, or government systems that mandate XML.

Using our JSON to XML converter is simple: paste your JSON data into the input field, optionally customize the root element name and formatting options, and the converted XML appears instantly in the output area. The converter automatically handles nested objects, arrays, and all JSON data types, transforming them into proper XML elements and attributes. Copy the resulting XML with a single click.

The converter maintains data structure while adapting to XML syntax, meaning objects become nested elements, arrays become repeated child elements, and values are properly escaped for XML. This ensures your XML output is well-formed, valid, and ready to use in any XML-compatible system. All conversion happens locally in your browser, keeping your data completely private.
