I know that i can loop through all 10 cells in a column and populate the column right next to it by
.Range("B" & cnt).Value = .Range("A" & cnt).Value + 1
but i can't stop wondering if i can perform a range-wise operation.

I've tried with
.Range("B" & cnt).Value = .Range("A" & cnt).Value + 1
but that didn't work. I've been laborating with "For Each" but that didn't worked out well. Any suggestions?
