Free No signup Client-side Privacy friendly

How to use

  1. 1 Paste your CSV / TSV / pipe-separated text.
  2. 2 Pick the delimiter and indicate whether the first row is a header.
  3. 3 Choose by column number (1-indexed) or by header name.
  4. 4 Copy the one-value-per-line output.

Why use this tool

  • RFC 4180 CSV parser handles quoted fields, escaped quotes, embedded newlines.
  • Pick by header name — column position changes do not break your workflow.
  • Custom delimiter for unusual separators (regex-free, plain string match).
  • Output one value per line — ready to paste into another tool or spreadsheet column.

Frequently asked questions

Are columns 0-indexed or 1-indexed?

1-indexed — column 1 is the leftmost. This matches how non-programmers think about spreadsheets.

What if a row is missing the picked column?

You get a blank line in the output for that row, so positional alignment with the input is preserved.

Does header-name match care about case?

Yes — case- and whitespace-sensitive after a single trim on each side. Pick "by number" if your headers are inconsistent.
