If you want to have a copy of a given column, you may want to duplicate that column.

You will duplicate two columns and use them as a base for recreating the email addresses.


  1. Click the column you want to duplicate, first_name in this example.
  2. Click the white menu icon or right-click the column to open the contextual menu.
  3. Click Duplicate column.

    A copy of the column, first_name_copy, is created with the same data as the original.

  4. Repeat these actions to duplicate the last_name column.


The two columns are duplicated. The information contained in those two column will be used to create the local part of the email addresses you want to create.
