Frequently asked questions

How are column headers cleaned?

Headers are trimmed, lowercased, and spaces are replaced with underscores. "Full Name" becomes "full_name". If there are no headers, columns are named column_1, column_2, etc.

What happens with quoted fields?

Fields wrapped in double quotes are handled correctly, even if they contain commas or newlines. This follows the RFC 4180 CSV standard.
