JSON to XML Converter
Convert JSON data into clean XML documents online with customizable root tags, element formatting, and automatic character escaping.
Run tool
This online JSON to XML converter transforms structured JSON text into valid XML markup. When converting data, each top-level object key becomes a child element enclosed within a configurable root element. Nested objects preserve their hierarchy as nested elements, while array items are wrapped in standard item tags or repeated parent names for primitive lists. The tool provides controls to customize the surrounding root tag name and toggle indented formatting. When formatting is enabled, the output includes an XML declaration along with clean indentation for improved readability. Invalid JSON syntax stops processing and highlights the issue so you can correct the input quickly. Characters requiring escaping inside element content are handled automatically during generation. Unsupported characters in property names, including leading digits, are sanitized into valid XML element tags. Provide your JSON payload to produce structured XML markup ready for configuration files, feeds, or data exchange.
Instructions
- Paste or type your JSON data into the input field.
- Enter a custom root element name if you prefer a different wrapping tag instead of the default root label.
- Select whether to format the XML with indentation and an XML header declaration.
- Run the conversion to view and copy the generated XML text.
Examples
- Converting a user profile object: Input: {"name": "Alex", "role": "developer"} Root Name: user Output: <?xml version="1.0" ?> <user> <name>Alex</name> <role>developer</role> </user>
- Converting a list of department items: Input: {"departments": ["Engineering", "Design"]} Root Name: company Output: <?xml version="1.0" ?> <company> <departments>Engineering</departments> <departments>Design</departments> </company>
FAQ
How are JSON arrays converted into XML elements?
Top-level array entries and object items inside arrays are enclosed within item elements. When a list of values is nested under an object property, the converter repeats the property name for each entry.
What happens if a JSON key contains characters not permitted in XML tag names?
Characters that are not allowed in XML tag names, such as spaces or special symbols, are replaced with underscores. Additionally, if a key starts with a digit, an underscore is prepended to ensure the tag name is valid.
What does the tool output if the input field is empty?
If the input field is empty or contains only whitespace, the tool treats it as invalid JSON and displays a parsing error message.
How does the converter handle an empty value entry?
Submitting an empty value literal generates a self-closing root tag corresponding to your chosen root element name.
