Filter duplicate records
In this article I will demonstrate a technique to filter duplicate records. The picture below shows you a data set in columns B to E. Next step is to create an Excel defined table.
Press with left mouse button on a cell in the table, go to tab "Insert" on the ribbon. Press with left mouse button on "Insert Table" button. The following dialog box appears.
Press with left mouse button on OK button.
Type Duplicate in cell F2 and then use the following formula in cell F3:
How the formula works in cell F13
Step 1 - Understand how relative and absolute cell references work
The formula uses absolute and relative cell references. In cell G3 the formula is:
=COUNTIFS($B$3:B3, B3, $C$3:C3, C3, $D$3:D3, D3, $E$3:E3, E3)>1
In cell G13 the formula has changed to:
=COUNTIFS($B$3:B13, B13, $C$3:C13, C13, $D$3:D13, D13, $E$3:E13, E13)>1
The cell ranges expand as the formula is copied to cells below. This lets you count the current record in above records.

Step 2 - Find duplicates
COUNTIFS($B$3:B13, B13, $C$3:C13, C13, $D$3:D13, D13, $E$3:E13, E13)>1
becomes
COUNTIFS({"Sample0"; "Sample0"; "Sample1"; "Sample0"; "Sample0"; "Sample1"; "Sample1"; "Sample0"; "Sample1"; "Sample1"; "Sample1"}, B13, {"B"; "B"; "A"; "A"; "B"; "B"; "B"; "A"; "A"; "A"; "A"}, C13, {11; 11; 11; 10; 10; 10; 11; 11; 10; 11; 11}, D13, {"AA111";"AA110";"AA111";"AA111";"AA110";"AA111";"AA111";"AA110";"AA110";"AA110";"AA111"}, E13)>1
becomes
=IF(COUNTIFS({"Sample0"; "Sample0"; "Sample1"; "Sample0"; "Sample0"; "Sample1"; "Sample1"; "Sample0"; "Sample1"; "Sample1"; "Sample1"}, "Sample1", {"B"; "B"; "A"; "A"; "B"; "B"; "B"; "A"; "A"; "A"; "A"}, "A", {11; 11; 11; 10; 10; 10; 11; 11; 10; 11; 11}, 11, {"AA111";"AA110";"AA111";"AA111";"AA110";"AA111";"AA111";"AA110";"AA110";"AA110";"AA111"}, "AA111")>1, "Duplicate", "")
becomes
=2>1
and returns TRUE in cell G13
How to use the COUNTIFS function
Checks multiple conditions against the same number of cell ranges and counts how many times all criteria are met.
