The CSV Column Extractor lets you keep only the columns you care about and drop everything else, producing a trimmed CSV with just the fields you selected. It's ideal for slimming down a wide export before importing it somewhere or sharing a subset of data. Processing runs locally in your browser, so sensitive columns never leave your device. To reorder or reshape further, pair it with the CSV Sorter or the CSV Filter.
