FAQ

What JSON does this converter support?

The converter accepts a JSON object as the root value and converts supported strings, numbers, booleans, arrays and nested objects into TOML.

Does the converter support nested objects?

Yes. Nested JSON objects are converted into TOML sections using dotted section names where appropriate.

Does this tool support null values?

TOML does not have a native null value, so JSON null values are rejected by this converter with an explanatory error message.

Is my JSON uploaded to a server?

No. The conversion is performed directly in your browser and your JSON data is not uploaded to our server.

Can I download the TOML result?

Yes. Use the Download TOML button to save the converted output as a TOML file.
