How to use CSV Column Extractor

Load your CSV, tick the columns to keep, reorder or rename them as needed, check the live preview, then download the trimmed CSV file.

Frequently asked questions

Why extract columns instead of deleting them in a spreadsheet?

Because a spreadsheet can silently reformat your data — dropping leading zeros from postcodes, turning long IDs into scientific notation or reinterpreting dates. This tool treats every field as text and only removes or reorders columns, so the values you keep are byte-for-byte the ones you had.

Can I change the order of the columns I keep?

Yes. Move any selected column up or down and the export follows that order exactly, which is handy when a target system expects its fields in a fixed sequence.

Can I rename the headers on the way out?

Yes. Each kept column has an editable output name, so you can map your internal field names onto whatever an import template or API expects without touching the data itself.
