How to use CSV Column Picker
Tick the columns to keep — output previewed exactly before export.
Prepare your input
Paste or load CSV with a header row.
Use the workspace
Tick only the columns you want to keep.
Check your result
Inspect the output header and a few complete records.
Know the limits
Removing a column changes the dataset. Keep a source copy if other workflows depend on omitted values.
