How to find out duplicate value on the row and delete it. Need help!

Hey Joco,

Take a look at my solution here. It marks rows with data that already appeared before as duplicates:

In that case each row has an ID, so to only search for duplicates in previous rows, I can filter those down to id < thisRow.id. If your table doesn’t have an ID system, you can create a Row ID column (e.g. by clicking the blue “add column” button → Properties → Row ID) and use that.
