CSV & TSV

The CSV editor opens .csv, .tsv, and .tab text files and starts in Table. The field delimiter follows the file’s extension — comma for .csv, tab for .tsv/.tab — for both reading and writing.

Interactive CSV editorEdit cells directly, drag across a range, and copy or paste. The real editor on an in-memory file — nothing is saved to a tray.

Views and actions

• Table presents every record as editable cells with spreadsheet-style column letters and row numbers. Double-click a cell, press Enter, or start typing to edit it.
• Raw exposes the delimited source directly, including quotes and line endings.
• Add row and Add column extend the table without hand-editing delimiters.

Quoted delimiters, escaped quotes, and line breaks inside quoted fields are preserved. Editing a cell only rewrites that one line, so the exact quoting of every row you leave untouched is kept byte-for-byte. If the source has an unfinished or malformed quoted field, Table asks you to repair it in Raw rather than guessing and rewriting the file.

Selecting and moving data

Click a cell to select it, or drag across cells to select a rectangular range. You can also hold Shift while using the arrow keys to extend the selection.

• Press Delete or Backspace to clear the selected cells. Their rows and columns stay in place.
• Copy a selection to put it on the clipboard as tabular text.
• Paste into a selected cell to fill from that point, growing the table when needed. A single copied value fills the whole selected range.

The tabular clipboard format works between Worktray CSV files and spreadsheet apps that copy cells as tab-separated values.

Undo and redo

Cmd/Ctrl+Z and Cmd/Ctrl+Shift+Z undo and redo across both views. See Getting started for the full model.
