Frequently asked questions (JSON to XML)

Does this tool support deeply nested JSON structures?

Yes. The converter recursively traverses objects and arrays, creating nested XML elements that mirror the original JSON hierarchy.

How are JSON arrays converted to XML?

Each item in an array becomes a repeated XML element under the same parent. For example, {"items": [1,2,3]} becomes <items>1</items><items>2</items><items>3</items>.

Are special characters escaped in the XML output?

Absolutely. Characters like <, >, &, single and double quotes are automatically replaced with their XML entity equivalents (<, etc.) to ensure valid XML.

Is my JSON data uploaded to a server?

No. The tool runs entirely in your browser. Your data never leaves your computer – even works offline after first load.

What if my JSON has keys that are invalid as XML element names?

The tool automatically sanitizes keys (e.g., removes invalid characters or replaces spaces with underscores) to generate valid XML element names. A warning is shown in the console.

Can I download the generated XML as a file?

Yes. Click “Download .xml” to save a standalone XML file with proper encoding and indentation. You can also copy the code directly to your clipboard.

Is this JSON to XML converter really free?

Yes, completely free. No hidden fees, no premium tiers, no watermarks. DataFrog believes essential developer tools should be accessible to everyone.
