- ＞1: This comparison operator checks if the count from the previous step is greater than 1. In other words, it evaluates to true if there is more than one occurrence of the value in B1 in column B, indicating a duplicate value.

In a nutshell, the formula =COUNTIF(B:B, B1)＞1 returns a logical value of TRUE if the value in cell B1 appears more than once in column B, and FALSE otherwise. It is commonly used to identify duplicate values in a column.
