Example #1 – VBA Remove Duplicates

We have a list of numbers starting from 1 to 5 till row 20 in column A only. As we can see in the below screenshot, all the numbers are getting repeated multiple times.

Now our job is to remove the duplicate from the list by VBA. For this go to the VBA window by pressing the F11 key.

In this example, we will see, basic use of how VBA Remove Duplicates can work for numbers. For this, we need a Module.

Step 1: Open a new Module from the Insert menu which is in the Insert menu tab.

Step 2: Once it is open write the subcategory of VBA Remove Duplicate as shown below.

Code:

Sub VBARemoveDuplicate1()

End Sub

Step 3: In the process of removing the duplicate, first we need to select the data. For this, in VBA we will Selection function till it goes down to select complete data list as shown below.

Code:

Sub VBARemoveDuplicate1()

Selection.End(xlDown).Select

End Sub

Step 4: Now we will select the Range of selected cells or columns A. It will go down till we have the data in a particular column. Not only till row 20.

Code:

Sub VBARemoveDuplicate1()

Selection.End(xlDown).Select
Range(Selection, Selection.End(xlUp)).Select

End Sub

Step 5: Now select the range of the cells in a currently opened sheet as shown below. This will activate the complete column. We have selected column A till the end.

Code:

Sub VBARemoveDuplicate1()

Selection.End(xlDown).Select
Range(Selection, Selection.End(xlUp)).Select
ActiveSheet.Range("A:A").

End Sub

Step 6: Now use RemoveDuplicate function here. This will activate the command to remove the duplicate values from the sequence of the columns 1. If there are more columns then the number will be added and separated by commas in the brackets as (1, 2, 3,…).

Code:

Sub VBARemoveDuplicate1()

Selection.End(xlDown).Select
Range(Selection, Selection.End(xlUp)).Select
ActiveSheet.Range("A:A").RemoveDuplicates Columns:=1,

End Sub

Step 7: Now we will use the Header command which will move the cursor to the topmost cell of the sheet, which is mostly in the header of any table.

Code:

Sub VBARemoveDuplicate1()

Selection.End(xlDown).Select
Range(Selection, Selection.End(xlUp)).Select
ActiveSheet.Range("A:A").RemoveDuplicates Columns:=1, Header:=xlYes

End Sub

Step 8: Now compile the code steps by pressing the F8 Key. Once done then click on the Play button to run to code as shown below.

As we can see, the duplicate number is deleted from column A and the only a unique count is left.

Example #2 – VBA Remove Duplicates

In this example, we will see how to remove duplicate values from more than one column. For this, we will consider the same duplicate list used in example-1. But in a new way, we have added 2 more columns of the same values as shown below.

This is another method with a little different type of code structure.

Step 1: Open a new module in VBA and write the subcategory in the VBA Remove Duplicate. If possible then give it a sequence number so that it will be better to choose the right code to run.

Code:

Sub VBARemoveDuplicate2()

End Sub

Step 2: First, select the complete sheet in VBA as shown below.

Code:

Sub VBARemoveDuplicate2()

Cells.Select

End Sub

Step 3: Now select the currently opened sheet with ActiveSheet command and select columns A to C as shown below.

Code:

Sub VBARemoveDuplicate2()

Cells.Select
ActiveSheet.Range("A:C").

End Sub

Step 4: Now select the RemoveDuplicates command and after that select Column array from 1 to 3 as shown below.

Code:

Sub VBARemoveDuplicate2()

    Cells.Select
    ActiveSheet.Range("A:C").RemoveDuplicates Columns:=Array(1, 2, 3),

End Sub

Step 5: At last use, the Header command to be included in the process of removing duplicates as xlYes as shown below.

Code:

Sub VBARemoveDuplicate2()

    Cells.Select
    ActiveSheet.Range("A:C").RemoveDuplicates Columns:=Array(1, 2, 3), Header:=xlYes

End Sub

Step 6: Now compile the complete code and run. As we can see below, the complete sheet is selected but the duplicate values are removed from columns A, B, and C, keeping only unique count.

Example #3 – VBA Remove Duplicates

This is another method of removing duplicate which is the simplest way to remove duplicate in VBA. For this, we will use the data which we saw in example-1 and also shown below.

Step 1: Now to go VBA and write subcategory again of VBA Remove Duplicates. We have given the sequence to each code we showed to have a proper track.

Code:

Sub VBARemoveDuplicate3()

End Sub

Step 2: This is quite a similar pattern which we have seen in example-2 but a shortcut way to write a code for removing duplicate. For this first directly start selecting the range of column as shown below. We have kept the limit till 100^th cell of column A starting from 1 followed by a dot(.)

Code:

Sub VBARemoveDuplicate3()

Range("A1:A100").

End Sub

Step 3: Now select the RemoveDuplicates command as shown below.

Code:

Sub VBARemoveDuplicate3()

Range("A1:A100").RemoveDuplicates

End Sub

Step 4: Now select the columns A as with command Columns with the sequence of 1. And after that include the Header of selected columns as well as shown below.

Code:

Sub VBARemoveDuplicate3()

Range("A1:A100").RemoveDuplicates Columns:=1, Header:=xlYes

End Sub

Step 5: Now compile it by pressing F8 key and run. We will see our code has removed the duplicate numbers from columns A and only unique values are pertained.
