Frequently Asked Questions

Does this tool detect data types?

Yes. Numbers and booleans are automatically detected and converted to their JSON equivalents instead of strings.

What about CSV files without headers?

You can toggle the headers option off. Without headers, each row becomes a JSON array of values instead of an object.
