What is JSON to XML Converter?
JSON to XML is a data format converter. Paste JSON such as {"name": "John", "age": 30} and click Convert to XML. The tool parses the JSON and outputs XML headed by the <?xml version="1.0" encoding="UTF-8"?> declaration, with a fixed <root> element, 2-space indentation, and array items repeated as same-named tags. Invalid JSON shows the exact parse error. Conversion happens locally — nothing is uploaded. Useful for API data migration, config conversion, and cross-system data exchange.

What is the JSON to XML converter?
An online data format tool. Input: valid JSON text. Output: formatted XML with a declaration and root element. Used for API migration, config generation, and data exchange. Runs entirely in your browser.
How are arrays represented in XML?
Each array item becomes a same-named tag — e.g., {"tags":["a","b"],"id":1} produces two <tags> elements.
Is the root element fixed?
Yes, everything is wrapped in <root> so the output is always well-formed XML.
What happens on invalid JSON?
A red error box shows the exact message from the JavaScript parser and the output is cleared.
Are nested objects supported?
Yes — nesting of any depth is expanded recursively with indentation.
Does the output include an XML declaration?
Yes, output starts with <?xml version="1.0" encoding="UTF-8"?>.
Is my data uploaded?
No. Parsing and conversion happen locally in your browser.
Can it handle boolean and number values?
Yes. Booleans become <tag>true</tag> or <tag>false</tag>. Numbers become <tag>42</tag>. Null values produce empty elements <tag/>.
What about special XML characters?
Characters like <, >, & in values are automatically escaped to <, >, & per XML specification.
Is there a size limit?
No hard limit. JSON up to 10MB converts in under 2 seconds. Larger files may work but could affect browser performance.
