Frequently Asked Questions

Does this tool upload my data?

No. All parsing and conversion are executed locally in your browser via JavaScript. Your data remains strictly confidential.

What happens if a cell is empty?

By default, empty cells are output as null or empty strings, depending on your configuration preferences.

Can it handle CSVs without headers?

Yes, you can configure the tool to treat the first row as data and generate generic keys (e.g., Column1, Column2) or output an array of arrays instead of objects.
