How do I select or remove columns from a CSV file?

Upload your CSV, then toggle the columns you want to keep or remove by clicking their tags. Switch between 'Keep selected' and 'Remove selected' mode, then click Apply. Download the resulting CSV with only the chosen columns.

Can I reorder columns with this tool?

The tool currently keeps columns in their original order and only selects a subset. The output preserves the same left-to-right order as the source CSV for the selected columns.

What happens if I select all columns to remove?

The tool prevents applying a filter that would result in zero columns — it shows an error and requires at least one column in the output before processing.

Can I use this to slim down a wide CSV with many columns?

Yes — this is the primary use case. If your CSV has 50 columns and you need only 5 for analysis, select just those 5 in 'Keep selected' mode and download the slimmed-down file instantly.

Is the CSV column picker free and private?

Yes — free, no account required, and your CSV never leaves your browser. All processing uses PapaParse on the client side.
