Can I reorder columns without removing any?

Yes, select all columns in whatever order you want them to appear in the output.

Does removing a column affect the data in the remaining columns?

No, each column's data is independent — removing one has no effect on the values in the others.

Can I rename columns while extracting them?

This tool focuses on selecting and reordering columns — renaming headers would need a text editor pass on the output file.

Does CSV Column Extractor upload my files to a server?

No. CSV Column Extractor runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

A CSV export often includes more columns than you actually need, or in an order that doesn't match what you're trying to do with the data — and manually deleting or reordering columns in a text editor is error-prone once there are more than a handful. This tool extracts and reorders specific columns from a CSV, letting you keep just what you need in the order you want it.
