JSON to XML Converter

Convert JSON Data for Legacy System Integration

Bridging the gap between modern REST APIs and legacy SOAP endpoints requires precise format translation. This JSON to XML Converter automatically parses your JavaScript Object Notation (JSON) and renders it into valid, hierarchical Extensible Markup Language (XML). This is essential for developers integrating new applications with older enterprise systems, configuration files, or strict data interchange protocols.

Unlike simple string replacers, this tool performs a recursive traversal of your data. It handles nested objects and arrays, ensuring the resulting XML tree is syntactically correct and ready for deployment. The entire conversion happens in your browser, guaranteeing your data never leaves your device.

Optimized Conversion Workflow

1. Input Data: Paste your JSON object (e.g., {"id": 1}) into the left panel.
2. Process: Click "Convert to XML." The engine parses the object tree and maps keys to XML tags.
3. Deploy: Copy the output, which is wrapped in a <root> element, directly into your codebase.

Frequently Asked Questions

How do you convert JSON to XML?

Paste your JSON into the input box and click "Convert to XML." The tool recursively iterates through keys and values, generating open and close tags for every property found, creating a valid XML document structure.

What is the main difference between JSON and XML?

JSON (JavaScript Object Notation) is a lightweight data format used primarily for web APIs and modern applications. XML (Extensible Markup Language) is a document-oriented format used for configuration, SOAP services, and complex document storage.

Why would you convert JSON to XML?

Interoperability is the main driver. Many legacy systems, financial gateways, and older enterprise service buses (ESBs) strictly require XML input. This tool allows modern JSON-based apps to communicate with these systems.

Can JSON have attributes like XML?

No. JSON data is strictly key-value pairs. This converter treats every JSON key as an XML element node. It does not attempt to guess which fields should be attributes, ensuring a predictable and standard output structure.

Does JSON to XML conversion lose data?

No data is lost, but the structure changes. Arrays in JSON become repeated elements in XML. For example, a JSON array of three items results in three identical XML tags appearing sequentially.
