JSON to XML Online

JSON to XML conversion transforms a JSON object or array into XML markup. Each JSON key becomes an XML element name and each value becomes its text content or a nested element. XML requires a single root element, which the converter adds automatically.

Each item in a JSON array becomes a repeated XML element using the array's key as the tag name. For example, {"items":["a","b","c"]} becomes three <items> elements. Since XML has no native array type, this repeated-element convention is the standard approach used by most JSON-to-XML converters.

The XML specification requires exactly one root element per document. JSON has no such restriction — an array or primitive value at the top level is valid. When converting JSON to XML, the converter automatically wraps the content in a <root> or <document> element to satisfy this requirement.

XML has no native numeric or boolean types — all content is text. Numbers and booleans are serialised as their string representations (e.g. 42 becomes the text "42", true becomes "true"). The type information is lost unless you add an XML Schema (XSD) or type attributes. Converting back to JSON requires knowing which text values should be parsed as numbers.

Yes — the XML to JSON tool reverses the conversion. The round-trip is not perfectly lossless: XML attributes are represented with an @ prefix in JSON, repeated sibling elements become arrays, and text content of elements becomes a # or _text key. The data is preserved but the structure may differ from the original JSON.
