Frequently asked questions
- Can I reorder the columns, not just remove some?
- Yes. You choose both which columns to keep and the order they appear in the result, so you can move an email column to the front or drop everything except a name and a total, without touching the source file.
- What if my CSV has no header row?
- Columns are then referred to by their position, so you can still pick the first, third and fourth columns by their slot. If a header row is present, columns are listed by name, which is easier to recognise.
- Does it keep my rows in the same order?
- Yes. Extracting columns only changes which columns appear and in what order; every row stays exactly where it was, so the output lines up one-to-one with the input.
- Is my file sent to a server?
- No. Everything runs locally in your browser. Your file is read and processed on your own device, nothing is uploaded, and nothing is logged or stored.
