About

Transforms JSON objects into well-formed XML with configurable root element names, case conversion (camelCase, snake_case, kebab-case, PascalCase), and intelligent array handling (wrapped/unwrapped). Supports attribute detection via @ prefix, CDATA sections for text-heavy content, and XML declaration toggle.

Many legacy systems, SOAP APIs, and configuration formats still require XML despite JSON's dominance. This tool provides a reliable bridge for data migration, API integration, and cross-format compatibility without manual XML authoring.

Who should use this tool?

Backend developers working with SOAP APIs, ETL pipeline engineers, DevOps automating XML configuration generation, and anyone migrating data from JSON to XML-based systems.

Common use cases

Convert JSON API responses to XML for SOAP-based web service consumption
Generate XML configuration files (like Ant, Maven, or Spring XML) from JSON templates
Transform JSON data exports into XML format for legacy system imports
Create XML sitemaps from JSON-structured website data
Convert JSON test fixtures to XML for testing XML-parsing code paths
Generate RSS/Atom feed XML from JSON blog post data structures

How to Use

Paste your JSON object into the input editor; the tool validates JSON syntax and parses the structure

Set the root element name in the configuration panel (defaults to "root" if not specified)

Configure array handling: choose "wrapped" (arrays get a parent wrapper element) or "unwrapped" (repeat the element name)

Enable attribute detection: keys prefixed with @ become XML attributes; nested objects become child elements

Toggle options: XML declaration, CDATA wrapping for long text, and case conversion for element names

Click "Convert" and review the XML preview; copy the result or download as .xml file

Examples

Input: {"person":{"@id":1,"name":"Alice","roles":["admin","user"]}} with array handling=wrapped -> Output: <?xml version="1.0" encoding="UTF-8"?><person id="1"><name>Alice</name><roles><role>admin</role><role>user</role></roles></person>

Input: {"data":{"content":"Hello <world>"}} with CDATA enabled -> Output: <?xml version="1.0"?><data><content><![CDATA[Hello <world>]]></content></data>

Best Practices

Use the @ prefix convention for attributes to keep the JSON intuitive and avoid manual XML attribute placement
Enable CDATA for fields containing HTML, special characters, or any content with angle brackets
Use "unwrapped" array style for simpler XML output when you don't need intermediate wrapper elements
Always specify a descriptive root element name instead of using the default "root" for production use
Preview the output with the XML declaration enabled to ensure encoding and version info are correct

Common Mistakes

Forgetting to prefix attributes with @ and then wondering why they appear as child elements instead
Using JSON arrays where the target XML schema expects single elements (check the array handling setting)
Not enabling CDATA for fields containing HTML or XML content, resulting in malformed output
Assuming nested key names are automatically sanitized; XML element names have stricter rules than JSON keys
Setting case conversion that conflicts with the target system's XML naming conventions or DTD

FAQ

Can I control the XML namespace (xmlns) generation? Namespace support is not automatic; you can add xmlns attributes using the @ prefix convention.

What happens if my JSON key starts with a number? The tool prepends an underscore or allowed character since XML elements cannot start with digits.

How is the XML declaration handled? You can toggle it on/off; when enabled it includes version and encoding attributes.

Does it support mixed content (text with child elements)? Not directly; use CDATA for text-heavy nodes that need to coexist with element children.
