Why Use Our JSON to XML Converter?
Frequently Asked Questions
How are JSON arrays converted to XML?
JSON arrays are converted to repeated XML elements. For example, {"items": [1, 2, 3]} becomes <items><item>1</item><item>2</item><item>3</item></items>. You can configure the singular element name used for array items.
Does the output include an XML declaration?
Yes. The converter includes the standard <?xml version="1.0" encoding="UTF-8"?> declaration at the top of the output. You can optionally remove it if your use case does not require it.
How are JSON null values represented in XML?
By default, null values are represented as empty self-closing elements (e.g., <field/>). You can also configure them to use an xsi:nil="true" attribute for XML Schema compliance.
