Copy and Pasting Columns Quickly

Is there a way to easily copy and paste columns instead of having to duplicate one at a time? I want to duplicate 15 columns a few times and it seems unnecessarily tedious, thanks!

It sounds like you’re talking about creating columns as opposed to populating them, and I think the answer is no.

However it has been a game-changer for me to find out that you can click the title of a column to select, then paste the data into another column. For example, copying an if-then column to a text column can be used the way you might use find and replace in a spreadsheet.
