通过行比较在Excel中对两行进行条件格式化

Question

Consider the following data:

I would like to compare each cell in row 1 to the adjacent cell below in row 2, using red for inequality and green for equality. A similar principle applies for rows 3 and 4. Ie, the output should be

The data I have in reality have more rows and columns than in this toy example, so the less manual work that has to be done, the better. The data I have are small enough that I would be fine pointing and clicking for results. I've tried using Conditional Formatting for this, but haven't been able to figure out its formulas.

I would prefer a non-VBA solution if possible.

I don't necessarily need the provided solution to be general, as long as it's clear to me how it can be generalized. Ie, it needs to be obvious how to adjust the solution when the data start at a different row or column, other than cell A1 .

Answer 1

Fill all the cells red then use this rule to turn them Green

=AND(A1<>"",OR(AND(MOD(ROW(A1)-1,2)=0,A1=A2),AND(MOD(ROW(A1)-1,2)=1,A1=INDEX(A:A,ROW(A1)-1))))

Answer 2

The following formula will format all pairs of nonequal cells:

=OFFSET(A1,1-2*MOD(ROW()+1,2),0)<>A1

Create a second rule with <> replaced with = to format the equal cells.
