Here's the problem:
There is a Column of alphanumeric codes. Each code is repeated multiple times. I'm trying to delete the rows with repeated codes so that I'm left with a spreadsheet of rows with only unique codes, no repeats.
I've been trying to match the code cell with the cell below it, and if that code = the reference code, delete entire row. But I'm having a ton of trouble with that.
I'm attaching an abridged example. The codes I'm referring to are in Column D. Can any one please help?
