JSON → XML

Does this JSON to XML tool upload my data to any server?

No. All parsing and XML generation happen entirely in your browser. Your JSON input and XML output never leave your device.

Why do I see an error saying the JSON is invalid?

The tool uses JSON.parse, which requires strict JSON syntax. Missing quotes, trailing commas, or malformed structures will cause a parsing error. Fix the JSON and try again.

How does the converter handle arrays?

Arrays are converted into repeated XML tags. If the root JSON value is an array, each item becomes an <item> tag inside the chosen root tag.

Why do object keys become tag names?

The tool uses a simple deterministic mapping: JSON objects become XML elements, and each key becomes a nested tag. This preserves structure in a predictable way.

What does the indentation setting control?

Indentation sets how many spaces are used for each XML nesting level. You can choose 2-space or 4-space formatting depending on your preferred style.

What is the purpose of the root tag name?

Every XML document must have exactly one root element. You can choose a custom root tag, or leave it as the default 'root'. Arrays are wrapped inside this tag.

Why are special characters escaped?

Characters like <, >, &, ", and ' are automatically escaped to ensure the XML remains valid and well-formed.

Can I upload a JSON file instead of pasting text?

Yes. You can upload a .json file, and its contents will be loaded directly into the input area for conversion.

Why can’t I download XML sometimes?

The Download button is enabled only when valid XML has been generated. If your JSON is invalid or empty, the output will be blank and downloading is disabled.
