The grid's context menu gets Copy as ▸ TSV / CSV / One-Row, and the
toolbar extractor drop-down gains One-Row: every selected value on one
", "-separated line — numbers bare, strings single-quoted with '
doubled, NULL for nulls — for pasting into IN (…) lists.
The toolbar extractor also decides what plain ⌘C copies, for CSV and
One-Row (JSON / SQL Inserts / Markdown stay TSV, keeping ⌘C
cell-shaped). TSV remains the default.
