Free JSON to XML Converter
JSON dominates modern APIs, but legacy systems, enterprise integrations, and configuration formats still expect XML. Converting between the two formats manually is error-prone — mismatched nesting, unescaped characters, and wrong root elements break parsers. Our free JSON to XML converter transforms JSON objects and arrays into valid XML instantly.
Paste your JSON, get formatted XML output, and copy it for your integration pipeline, config file, or documentation.
How to Use the JSON to XML Converter
Paste valid JSON into the input field. The converter parses the structure and generates equivalent XML with proper element nesting, array handling, and character escaping. Review the output for root element naming and attribute mapping. Copy the XML for use in your application or save it for migration scripts.
Why JSON to XML Converter Matters
Enterprise SOAP services, SAML identity providers, RSS feeds, and Android layout files all use XML. When modern JSON APIs need to feed legacy XML systems, automated conversion saves hours of manual transformation. Developers migrating configs from JSON to XML-based formats rely on converters for accurate structural mapping.
Who Uses a JSON to XML Converter?
- Integration developers convert JSON API responses to XML for legacy system feeds.
- Backend developers transform data between microservices using different formats.
- Data engineers migrate configuration files between JSON and XML schemas.
- QA testers generate XML test fixtures from JSON API mock data.
- Technical writers produce XML examples from JSON API documentation.

Tips for Getting the Most From This Tool
JSON arrays typically become repeated XML elements with the same tag name. Specify a root element name if the tool supports it — default roots like root or data work for most cases. Validate output XML against your target schema if one exists.
Frequently Asked Questions
How are JSON arrays converted to XML?
Each array item becomes a repeated child element. For example, [1, 2, 3] might become <item>1</item><item>2</item><item>3</item> under a parent element.
Are JSON attributes supported?
Standard JSON has no attribute concept. All JSON keys become XML elements. Some converters map keys starting with @ to XML attributes.
Is my data sent to a server?
No. Conversion runs entirely in your browser.
What about invalid JSON?
The converter shows a parse error if your input is not valid JSON. Fix syntax errors before converting.
