Duplicates

Remove duplicate rows from a CSV

Lists merged by hand often hold the same row twice. Remove duplicates keeps the first of each and says how many it removed.

When this helps

Use this for mailing lists, exports joined from several files, or any list where each row should appear once.

For example

A task you can finish here

A sign-up list where some people registered twice: choose the email column, Only by the chosen column, and Remove duplicates keeps each address’s first row.

The workflow

Three clear steps

  1. 01

    Open the list

    Edit says how many rows repeat before you remove them.

  2. 02

    Remove duplicates

    Compare every column, or choose columns and compare only them. Trim spaces first to also catch rows that differ only by spaces.

  3. 03

    Save a copy

    Undo brings the rows back if the count is not what you expected.

Questions

Does it compare similar rows, such as “Jon” and “John”?

No. Only exact repeats, after trimming if you choose Trim spaces.
