If you need to find duplicates in a range of cells rather than in an entire column, remember to fix that range by using $. For example, to search for duplicates in cells A2:A8, use the formula =COUNTIF( $A$2:$A$8, A2)>1. IF( SUM(( --EXACT( range, uppermost _cell)))1, 'Duplicate row', ') The following screenshot demonstrates that the formula really locates only the rows that have identical values in all 3 columns. For example, row 8 has the same order number and date as rows 2 and 5, but a different item in column C, and therefore it is not marked as duplicate row: To show duplicate rows without 1 st occurrences, make a little adjustment to the above formula: =IF(COUNTIFS($A$2:$A2,$A2,$B$2:$B2,$B2,$B$2:$B2,$B2,$C$2:$C2,$C2,) >1, 'Duplicate row', ') How to count duplicates in Excel If you want to know the exact number of identical records in your Excel sheet, use one of the following formulas to count duplicates. Count instances of each duplicate record individually When you have a column with duplicated values, you may often need to know how many duplicates are there for each of those values. To find out how many times this or that entry occurs in your Excel worksheet, use a simple COUNTIF formula, where A2 is the first and A8 is the last item of the list: =COUNTIF($A$2:$A$8, $A2) As demonstrated in the following screenshot, the formula counts the occurrences of each item: ' Apples' occurs 3 times, ' Green bananas' - 2 times, ' Bananas' and ' Oranges' only once. If you want to identify 1 st, 2 nd, 3 rd, etc. Occurrences of each item, use the following formula: =COUNTIF($A$2:$A2, $A2) In a similar manner, you can count the occurrences of duplicated rows.
