CSV Column Extractor

About this tool

The column extractor lets you keep only the columns you need from a spreadsheet and drop the rest. Upload a file, tick the columns to keep, drag them into the order you want, and download a slimmer CSV.

Exports from suppliers, apps, and marketplaces often carry dozens of columns you will never import. Pulling out the handful that matter makes the file smaller and easier to map when you bring it into Shopify. It reads .csv and .xlsx.

1. Upload your fileAdd a .csv or .xlsx export. Headers are detected automatically.
2. Pick and reorder columnsSelect the columns to keep and drag them into the order you want.

Frequently asked questions

Can I change the column order?

Yes. Drag the selected columns into any order before downloading, so the output matches the layout you need — handy for lining up columns before a horizontal join in the CSV Merge tool.

Does it work with Excel files?

Yes. Upload .xlsx and the tool reads the first sheet's columns the same way it reads a CSV.

Will the original file be changed?

No. The tool builds a new CSV from your selection. Your source file stays untouched on your device.
