I need to identify differences in adjacent &nbsp;row entries. &nbsp;For example data in row A1:H1 should match exactly data in the adjacent row, A2:H2 and data in A2:H2 should match exactly with data in A3:H3, and data in A3:H3 should match exactly with data in A4:H4, and so on. &nbsp;I really need to identify those that do not match exactly. I have 7000 rows to compare.
