Please see attached files. I need kcode1 to end up looking like kcode2. Reason being is, there is just under 5500 different numbers in the first column spread over 275000 plus rows.
First remove duplicates from column A. & paste the same in column C In column D Use the index formula & in later cells concatenate. Attached the file with the formula.
Thank You to yourself and srinidhi for coming back to me. Somebody came back to me on a different forum with the same example but with out the rather helpful do kodes button.
