JSON to XML Converter
Convert JSON objects to well-formed XML documents instantly in your browser.
JSON to XML Features
Clean, well-formed XML output from any valid JSON.
Output is always valid, well-formed XML.
JSON arrays become repeated XML elements.
Specify a custom root element name.
Key Takeaways
- Conversion runs entirely in your browser, so your JSON is processed on your device.
- Each object key becomes an element and arrays expand into repeated sibling elements that reuse the parent tag with no wrapper, so nest an array inside an object key if your schema needs a container element.
- The output uses elements only with no way to map a JSON field into an XML attribute, so adjust the markup afterward if your target schema requires attributes.
- Tag names come from JSON keys, so invalid characters are replaced with underscores and names starting with a digit get an underscore prefix, and the input must be strict JSON with double quotes and no trailing commas or comments.
How to Convert JSON to XML
Paste valid JSON and set a root name
Paste a JSON object or array into the input area. Optionally type a name in the Root Element Name field; if you leave it blank, the output is wrapped in a tag called root. The conversion runs in your browser, so the JSON stays on your device.
Click Convert to XML
The tool parses your input and builds well-formed XML. Each object key becomes an element, arrays expand into repeated elements that share the same tag, and the result is indented with two spaces under an XML declaration. If the JSON is invalid, the input is highlighted and the exact parser error is shown.
Copy the result or start over
Use Copy Result to send the generated XML to your clipboard for pasting into a file, API request, or config. Click Clear to empty both panels and reset the status message before converting a different payload.
How JSON Values Map to XML
The converter walks your JSON recursively and applies fixed rules for each value type. Knowing these rules helps you predict the markup and structure your JSON so the output matches what a target system expects.
| JSON value | XML output | Example |
|---|---|---|
| String or number | Element with the value as text content | "name": "Ada" becomes |
| Object | Element containing one child element per key | {"a": 1} becomes 1 inside the parent |
| Array | Repeated elements sharing the parent tag, no wrapper | "tag": [1,2] becomes |
| null | Self-closing empty element | "x": null becomes |
| Empty object | Self-closing empty element | "x": {} becomes |
| Reserved characters | Escaped to entities in text content | & < > " ' become & < > " ' |
Is This Converter Right for Your Data
Good for nested objects
Plain JSON objects translate cleanly: every key becomes a child element and nesting is preserved, producing readable, indented XML for configs, sample payloads, and documentation.
Good for simple arrays
Arrays turn into repeated elements that reuse the parent tag name, which matches how many legacy XML schemas express lists of items without a separate wrapper element.
Not for XML attributes
Output uses elements only. There is no syntax to map a JSON field into an attribute like id="5", so if your target schema requires attributes you will need to adjust the markup afterward.
Mind the key names
Tag names are derived from JSON keys. Characters that are not letters, digits, underscore, hyphen, or dot are replaced with underscores, and a leading underscore is added if a name starts with a digit.
Common Problems and Fixes
It says Invalid JSON
The input must be strict JSON, not a JavaScript object literal. Use double quotes around every key and string, remove trailing commas and comments, and check the error message, which reports the position where parsing failed.
My tag names changed unexpectedly
A key like "first name" or "2024" is not a legal XML tag. Spaces and other invalid characters become underscores, and names that start with a digit get an underscore prefix, so first_name and _2024 are expected and intentional.
Array items are missing a wrapper
Arrays produce repeated sibling elements rather than a container plus item tags. If your schema needs a wrapper, nest the array inside an object key, for example {"items": [ ... ]}, so items becomes the surrounding element.
An element looks empty
JSON null, empty objects, and empty arrays render as self-closing tags such as
