如何为 Excel 中的唯一值使用唯一颜色对列中的重复项进行颜色格式化？

Question

I have a column with multiple duplicates.

Is there a simple way, to have the unique values filled with the same unique colors?

Ex. if I have this column

Col A
a
a
a
b
b
b
c
c
c

the a values will be filled with yellow, the b values filled with red, the c values filled with green. But I don't know the "exact text" values (He in the example I know the value 'a', 'b' and 'c'. But in reality I don't know the exact text. I just know there are duplicates). So this must be generic..

Answer 1

This requires that the first row is a header and data must be sorted:

Use conditional formatting with the following formula:

=ISODD(SUMPRODUCT(--(A$2:A2<>A$1:A1)))
