Thanks SamT. I apologise that I wasn't clear.

I attach a sample workbook which contains:

1) Worksheet "Original input" with 93 rows of random text (there's no significance in the 93 - it's random)
2) Worksheet "Desired output" which I created manually to show the result once the macro has operated.

The macro will:

a) Delete, from "Original input", all rows where all columns are duplicated except those rows with NAME in column A.
b) Keep the rows in the same order.
c) Keep any row with NAME in column A, regardless of whether the remaining columns have duplicated cells.
d) Overwrite the worksheet "Original input" with the result. I just want to keep the end product, not the raw data.

I hope that's easier to work with. I'm very grateful to you and the other experts on the forum for your help.
