Can I convert XML back to JSON?

Yes. Click the 'XML → JSON' button to switch directions. Paste your XML and the tool converts it back to JSON format. The direction toggle is right at the top of the tool.

What happens to JSON arrays when converted to XML?

JSON arrays are converted to repeated XML elements with the tag name 'item'. For example, [1, 2, 3] becomes three separate elements. When converting back to JSON, sibling elements with the same tag name are automatically converted back to an array.

Does this tool handle nested JSON objects?

Yes. Nested JSON objects are recursively converted to nested XML elements. Each key becomes a tag, and the hierarchy is preserved through indentation.

Is my data sent to a server?

No. All conversion happens entirely in your browser using JavaScript. Your JSON or XML data never leaves your device, ensuring complete privacy.

Are there any size limits for conversion?

There's no hard limit since processing happens locally in your browser. Very large files (over 5MB) may slow down slightly depending on your device, but there's no server-side restriction.
