JSON to XML conversion transforms JSON data into XML format. This is useful when integrating with legacy systems, SOAP APIs, or services that require XML input. CodBolt's tool handles the conversion instantly in your browser — no data sent to any server.
When Repeat Elements is enabled (default), each item in a JSON array repeats the parent element tag — e.g. multiple <book> tags. When disabled, the array is wrapped in a parent element with <item index="n"> children instead.
Enable Attribute Support. Then prefix a JSON key with @ to make it an XML attribute. For example, {"@id": "101", "name": "Alice"} produces <root id="101"><name>Alice</name></root>. Use the #text key to set inline text content alongside attributes.
The tool automatically sanitizes JSON keys for XML compatibility. Special characters are replaced with underscores, and keys starting with a digit or invalid character are prefixed with _. For example, a key named 1item becomes _1item in the XML output.
If your JSON has exactly one top-level key, that key is automatically used as the XML root element name. For example, {"catalog": [...]} produces <catalog>...</catalog> as the root — instead of the default <root> wrapper.
You can upload JSON files up to 100MB. All processing is done locally in your browser — your data is never sent to any server.
