The two formulas will become =COUNTIF($D$2:$D$105, $D2) and =COUNTIF(D:D, D2). You can use the above formula without the > 1 text to count the number of duplicates in a column. Count the Number of Duplicates Using a Formula If you want to show only the duplicate values and not the first occurrence of the value, try this instead: =IF(COUNTIFS($D$2:$D2,$D2,$E$2:$E2,$E2,$F$2:$F2,$F2) >1, "Duplicate", "Unique") This only shows "Duplicate" for the second or more occurrences.ĥ.If any of the three is unique in a row, "Unique" will display instead. If you want to compare multiple columns at once, you'll need to use absolute cell references and an IF statement, such as: =IF(COUNTIFS($D$2:$D$105,$D2,$E$2:$E$105,$E2,$F$2:$F$105,$F2) >1, "Duplicate", "Unique") This formula will only show "Duplicate" if the values in D, E, and F are the same.You can easily use any words you want, such as "Duplicate" and "Unique." This will show "Duplicate" for duplicates and a blank cell for unique values. If you want to show something other than True or False, enclose COUNTIF inside an IF function: =IF(COUNTIF($D$2:$D$105, $D2) > 1, "Duplicate", " "). ![]() For instance, I'd use =COUNTIF($D$2:$D$105, $D2) >1 to check the entire D column.
