CSV Column Extractor
Keep, reorder or drop CSV columns in seconds
Runs 100% in your browser — nothing is ever uploaded.
What is CSV Columns?
Select exactly the columns you need — by position (1,3,5) or by header name (name,email) — and get a clean CSV with just those columns in your chosen order. Quoting is preserved, making this the fastest way to slim down exports before importing elsewhere.
How to use CSV Columns
- Paste your CSV into the input box or click “Load sample” to try it.
- Adjust the options in the toolbar if needed (delimiter, table name, format …).
- Click the convert button — the reduced CSV appears instantly in the output pane.
- Copy the result with one click or download it as a file.
