Frequently Asked Questions

What if my CSV doesn't have headers?

The converter assumes the first row contains headers. If your CSV lacks headers, add them manually as the first line before conversion.

How are commas inside fields handled?

Fields containing commas must be enclosed in double quotes (standard CSV escaping). The converter correctly handles these quoted fields and preserves the commas as data.
