Untick the columns you do not need and download a slimmer CSV, quoting kept intact
Processed in your browser. Nothing is uploaded. Checked against sources on 17 Oct 2026.Exports from shops, banks and CRMs carry dozens of columns nobody asked for. Drop the CSV here and each column is listed with a sample value from the first row that has one; untick the ones you do not need, or remove every empty column with one press, and download. Values are copied exactly, quoted fields with commas or line breaks stay intact, and a semicolon or tab file keeps its delimiter.

A spreadsheet export rarely has exactly the columns the next step needs. An import form wants five columns in a fixed order; a report from a shop or bank has forty, half of them empty. Doing this in a text editor breaks quoted fields, and opening a large CSV in Excel can change numbers such as phone numbers and long IDs.
| Action | How |
|---|---|
| Delete columns | Untick them |
| Delete every empty column | One press; the count is shown |
| Change the order | Up and down arrows on each column |
| Rename a header | Type in the column's box |
| Start over | Reset |
What does not change. Values are copied exactly, cell by cell. A CSV is written back with its own delimiter, comma, semicolon, tab or pipe, and with proper quoting, so values containing commas, quotes or line breaks stay whole. An Excel file comes back as an .xlsx, with the numbers, dates and number formats of the kept columns unchanged; formulas are saved as their results.
The rest of the article, and all 6 questions about CSV Column Editor, are on the CSV Column Editor page.

Yes. Type a new name in any column's box and the header row of the download uses it. The page warns when two kept columns would end up with the same name, which many importers and databases reject.
Yes. Drop an .xlsx and choose the sheet if there are several. The download is an .xlsx with the kept columns' numbers, dates and number formats unchanged. Formulas are saved as their calculated values, because the columns they refer to may have moved.
