Remove a CSV Column

Enter the exact name of a column to completely remove it from a CSV file, header included.

Example:
Drag and drop a .csv file here, or paste the content below.

How it works

Useful when an export contains an internal column, a technical identifier, or sensitive data you want to remove before sharing the file. Enter the name of the column as it appears in the header, and it is removed from all rows.

What happens if the column name entered does not exist?

A clear error is displayed indicating that the column cannot be found. Check the exact spelling (including capitalization and spaces) as it appears on the first line of the CSV.

Can I remove multiple columns at once?

This tool removes one column at a time. To remove several, reuse the result as input and repeat the operation for each additional column.
