## 6 Ways to Count Duplicate Values in Multiple Columns in Excel

Here, we have the sales records of a company containing the records for *January *and *February *and we will try to count the duplicate sales values between the ** January **and

**columns.**

*February*We have used *Microsoft Excel 365* version here, you can use any other versions according to your convenience.

__Method-1__: Using COUNTIF Function to Count Duplicate Values in Multiple Columns

Here, we will use the **COUNTIF function** to count the duplicate sales values between the ** January **and

**columns and so that we have added an extra column**

*February***Helper**.

** Steps**:

âž¤ Type the following formula in cell

**E4**

`=COUNTIF($C$4:$D$11,C4)`

Here, **$C$4:$D$11 **is the range, **C4 **is the criteria corresponding to the cell with the formula.

âž¤ Press **ENTER **and drag down the **Fill Handle **tool.

Then, you will get **2 **for the duplicate values in the two columns as you can see the duplicate values have been indicated with red, blue, and green color boxes.

Now, we will count the number of duplicate values by using the following formula

`=COUNTIF(E4:E11,2)`

Here, **E4:E11 **is the range and **2 **is the criteria for indicating duplicates.

After pressing **ENTER**, you will get ** 3 **as the number of the duplicate values between the

**January**and

**February**columns.

__Method-2__: Combination of SUM, IF, ISNA, and MATCH Functions to Count Duplicate Values

In this section, we will be using the **SUM function**, **IF function**, **ISNA function**, and **MATCH function** to count the duplicate values in the ** January **and

**columns.**

*February*** Steps**:

âž¤ Type the following formula in cell

**D12**

`=SUM(IF(ISNA(MATCH($C$4:$C$11,$D$4:$D$11,0)),0,1))`

Here, **$C$4:$C$11 **is the range of the ** January **column and

**$D$4:$D$11**is the range of the

**column.**

*February*returns the relative position of the duplicate values in the range`MATCH($C$4:$C$11,$D$4:$D$11,0)`

â†’**$D$4:$D$11**corresponding to the range**$C$4:$C$11**.**Output â†’**`{#N/A;3;#N/A;#N/A;8;#N/A;#N/A;4}`

returns`ISNA(MATCH($C$4:$C$11,$D$4:$D$11,0))`

â†’ ISNA**TRUE**for**#N/A**error otherwise**FALSE****Output â†’**`{TRUE;FALSE;TRUE;TRUE;FALSE;TRUE;TRUE;FALSE}`

return`IF(ISNA(MATCH($C$4:$C$11,$D$4:$D$11,0)),0,1)`

â†’ IF**0**for**TRUE**and**1**for**FALSE****Output â†’**`{0;1;0;0;1;0;0;1}`

becomes`SUM(IF(ISNA(MATCH($C$4:$C$11,$D$4:$D$11,0)),0,1))`

`SUM({0;1;0;0;1;0;0;1})`

**Output â†’**3

After pressing **ENTER**, you will get the total number of duplicate sales values as **3 **between the ** January **and

**columns.**

__Method-3__: Using AND Function, COUNTIF Function to Count Duplicate Values in Multiple Columns

Here, we will use the **AND function**, **COUNTIF function** to count the duplicate sales values between the ** January **and

**columns.**

*February*** Steps**:

âž¤ Type the following formula in cell

**E4**

`=AND(COUNTIF($C$4:$C$11,C4),COUNTIF($D$4:$D$11,C4))`

Here, **$C$4:$C$11 **is the range of the ** January **column and

**$D$4:$D$11**is the range of the

**column.**

*February*returns the number of the value in cell`COUNTIF($C$4:$C$11, C4)`

â†’**C4**in the range**$C$4:$C$11****Output â†’**1

returns the number of the value in cell`COUNTIF($D$4:$D$11, C4)`

â†’**C4**in the range**$D$4:$D$11****Output â†’**0

becomes`AND(COUNTIF($C$4:$C$11,C4),COUNTIF($D$4:$D$11,C4))`

`AND(1,0)`

**Output â†’**FALSE

âž¤ Press **ENTER **and drag down the **Fill Handle **tool.

In this way, you will get **TRUE **for the duplicate values and **FALSE **for the unique values and now we will count the number of **TRUE **in the ** Helper **column to get the number of duplicate values.

âž¤ Type the following formula in cell **E12**

`=COUNTIF(E4:E11,TRUE)`

Here, **E4:E11 **is the range, and **TRUE **is the criteria.

âž¤ Press **ENTER**.

Finally, you will be able to count the duplicate values in the ** January **and

**columns which are**

*February***3**.

You can use the **SUMPRODUCT function**, **COUNTIF function** to count the duplicate values in the columns; ** January **and

**.**

*February*** Steps**:

âž¤ Type the following formula in cell

**D12**

`=SUMPRODUCT(COUNTIF($C$4:$C$11,$D$4:$D$11))`

Here, **$C$4:$C$11 **is the range of the ** January **column and

**$D$4:$D$11**is the range of the

**column.**

*February*gives the matched number of cells between the ranges`COUNTIF($C$4:$C$11,$D$4:$D$11)`

**$C$4:$C$11**and**$D$4:$D$11****Output â†’**`{0;0;1;1;0;0;0;1}`

becomes`SUMPRODUCT(COUNTIF($C$4:$C$11,$D$4:$D$11))`

`SUMPRODUCT({0;0;1;1;0;0;0;1})`

**Output â†’**3

âž¤ Press **ENTER**.

Afterward, you will get the number of duplicate values in the ** January **and

**columns which is**

*February***3**.

__Method-5__: Combination of SUMPRODUCT, ISNUMBER, MATCH Functions to Count Duplicate Values

Here, we will use the **SUMPRODUCT function**, **ISNUMBER function**, **MATCH function **to determine the duplicates between the ** January **and

**columns.**

*February*** Steps**:

âž¤ Type the following formula in cell

**D12**

`=SUMPRODUCT(--(ISNUMBER(MATCH($C$4:$C$11,$D$4:$D$11,0))))`

**$C$4:$C$11 **is the range of the ** January **column and

**$D$4:$D$11**is the range of the

**column.**

*February*returns the relative position of the duplicate values in the range`MATCH($C$4:$C$11,$D$4:$D$11,0)`

â†’**$D$4:$D$11**corresponding to the range**$C$4:$C$11**.**Output â†’**`{#N/A;3;#N/A;#N/A;8;#N/A;#N/A;4}`

becomes`ISNUMBER(MATCH($C$4:$C$11,$D$4:$D$11,0))`

`ISNUMBER({#N/A;3;#N/A;#N/A;8;#N/A;#N/A;4})`

**Output â†’**`{FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE}`

becomes`--(ISNUMBER(MATCH($C$4:$C$11,$D$4:$D$11,0)))`

Double negation (â€“) will convert`--({FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE})`

â†’**TRUE**into**1**and**FALSE**into**0****Output**â†’`({0;1;0;0;1;0;0;1})`

becomes`SUMPRODUCT(--(ISNUMBER(MATCH($C$4:$C$11,$D$4:$D$11,0))))`

`SUMPRODUCT({0;1;0;0;1;0;0;1})`

**Output â†’**3

After pressing **ENTER**, you will get the total number of duplicate sales values between the ** January **and

**columns.**
