About JSON XML Converter
This JSON XML converter switches data between JSON and XML so you can work with both modern APIs and older XML-based systems from one page.
JSON to XML Conversion Rules
- Object keys become XML element tags
- String/number/boolean values become element text content
- Arrays become repeated elements with the same tag name
- Nested objects become nested element hierarchies
- @attributes key becomes XML attributes on the parent element
- #text key becomes text content mixed with attributes
Conversion Example
JSON Input:
{
"book": {
"@attributes": { "id": "123" },
"title": "The Great Gatsby",
"author": "F. Scott Fitzgerald",
"year": 1925
}
}
XML Output:
<book id="123"> <title>The Great Gatsby</title> <author>F. Scott Fitzgerald</author> <year>1925</year> </book>
Common Use Cases
- API Integration: Convert REST API JSON responses to XML for SOAP services
- Feed Processing: Transform JSON data to RSS/ATOM XML feeds
- Legacy Systems: Interface modern JSON apps with XML-based enterprise systems
- Config Migration: Convert configuration files between JSON and XML formats
- Data Export: Generate XML for systems that require XSD validation
Frequently Asked Questions
- How is JSON converted to XML?
- JSON to XML conversion maps JSON keys to XML element tags and values to element content. Objects become nested element hierarchies, arrays become repeated elements with the same tag name, and primitive values become text content. Attributes can be represented using special keys like @attributes.
- What is the difference between JSON and XML?
- JSON is lighter and more concise, using key-value pairs and arrays. XML is more verbose with opening/closing tags and supports attributes, namespaces, and schemas. JSON is preferred for modern web APIs; XML is common in enterprise systems, SOAP APIs, and legacy integrations.
- When should I use JSON vs XML?
- Use JSON for: modern REST APIs, JavaScript applications, mobile apps, and lightweight data exchange. Use XML for: SOAP web services, document markup, RSS/ATOM feeds, enterprise integrations, and when you need schema validation (XSD) or transformations (XSLT).
- Does this tool preserve data types during conversion?
- JSON to XML conversion preserves string values directly. Numbers and booleans become text content in XML elements. When converting back, type inference depends on the XML content. Arrays become repeated elements; objects become nested element hierarchies.
