Frequently Asked Questions
Does it handle quoted CSV fields?

Yes. Fields wrapped in double quotes are handled correctly, including fields with commas inside quotes.

Can I use tabs or semicolons as delimiters?

Yes. Use the Delimiter dropdown to switch between comma, tab, and semicolon.

Is my CSV data uploaded?

No. All processing happens in your browser —nothing is sent to a server.

Does the first row have to be a header?

Yes, the tool treats the first row as column headers. If your CSV has no header row, the column names will be the raw values from the first row.
