CSV Column Extractor

Column extraction lets you pull out only the fields you need from a CSV file. This is useful when cleaning up data exports that contain dozens of columns but you only need three or four, removing sensitive columns like email addresses or phone numbers before sharing a file, preparing a focused import file for a system that expects specific columns, or reducing file size by dropping unnecessary data.

Instead of opening the file in a spreadsheet and manually deleting columns, paste your CSV here and select the columns you want to keep. The tool outputs a clean CSV with only your chosen columns, preserving the original order and quoting.

The tool reads the first row of your CSV and treats it as column headers. These headers appear as checkboxes you can toggle to include or exclude each column. If your CSV does not have a header row, the tool generates labels like Column 1, Column 2, and so on.

Column order in the output matches the order you select them. If your original file has columns A, B, C, D and you select C then A, the output will have C first and A second. This makes it easy to reorder columns at the same time as extracting them.
