## How to extract unique values from multiple columns in Excel?

Supposing you have several columns with multiple values, some values are repeated in same column or different column. And now you want to find the values which are present in either column only once. Are there any quick tricks for you to extract unique values from multiple columns in Excel?

#### Extract unique values from multiple columns with formulas

This section will cover two formulas: one using an array formula suitable for all Excel versions, and another using a dynamic array formula specifically for Excel 365.

##### Extract unique values from multiple columns with Array formula for all Excel versions

For users with any version of Excel, array formulas can be a powerful tool for extracting unique values across multiple columns. Here’s how you can do it:

1. Assuming your values in range A2: C9, please enter the following formula into cell E2:

``=INDIRECT(TEXT(MIN(IF((\$A\$2:\$C\$9<>"")*(COUNTIF(\$E\$1:E1,\$A\$2:\$C\$9)=0),ROW(\$2:\$9)*100+COLUMN(\$A:\$C),7^8)),"R0C00"),)&""``
Note: In the above formula, A2:C9 indicates the range of cells which you want to extract the unique values, E1:E1 is the first cell of the column you want to place the result, \$2:\$9 stands fro the rows contain the cells you want to use, and \$A:\$C indicates the columns contain the cells you want to use. Please change them to your own.

2. Then press Shift + Ctrl + Enter keys together, and then drag the fill handle to extract the unique values until blank cells appear. See screenshot:

Explanation of this formula:
1. \$A\$2:\$C\$9: This specifies the data range to be checked, which is the cells from A2 to C9.
2. IF((\$A\$2:\$C\$9<>"")*(COUNTIF(\$E\$1:E1,\$A\$2:\$C\$9)=0), ROW(\$2:\$9)*100+COLUMN(\$A:\$C), 7^8):
• \$A\$2:\$C\$9<>"" checks whether the cells in the range are not empty.
• COUNTIF(\$E\$1:E1,\$A\$2:\$C\$9)=0 determines if the values of these cells have not yet been listed in the range of cells from E1 to E1.
• If both conditions are met (i.e., the value is not empty and not yet listed in column E), the IF function calculates a unique number based on its row and column (ROW(\$2:\$9)*100+COLUMN(\$A:\$C)).
• If the conditions are not met, the function returns a large number (7^8), which serves as a placeholder.
3. MIN(...): Finds the smallest number returned by the IF function above, corresponding to the location of the next unique value.
4. TEXT(...,"R0C00"): Converts this minimum number into an R1C1 style address. The format code R0C00 indicates the conversion of the number into Excel cell reference format.
5. INDIRECT(...): Uses the INDIRECT function to convert the R1C1 style address generated in the previous step back to a normal A1 style cell reference. The INDIRECT function allows cell referencing based on the content of a text string.
6. &"": Appending &"" at the end of the formula ensures the final output is treated as text, so even numbers will be displayed as text.

##### Extract unique values from multiple columns with formula for Excel 365

Excel 365 supports dynamic arrays, making it much easier to extract unique values from multiple columns:

Please enter or copy the following formula into a blank cell where you want to put the result, and then click Enter key to get all the unique values at once. See screenshot:

``=UNIQUE(TOCOL(A2:C9,1))``

7. Then check the field Value or drag the Value to the Rows label, now you will get the unique values from the multiple columns as follows:

#### Extract unique values from multiple columns with VBA code

With the following VBA code, you can also extract the unique values from multiple columns.

1. Hold down the ALT + F11 keys, and it opens the Microsoft Visual Basic for Applications window.

2. Click Insert > Module, and paste the following code in the Module Window.

VBA: Extract unique values from multiple columns

``````Sub Uniquedata()
'Updateby Extendoffice
Dim rng As Range
Dim InputRng As Range, OutRng As Range
Set dt = CreateObject("Scripting.Dictionary")
xTitleId = "KutoolsforExcel"
Set InputRng = Application.Selection
Set InputRng = Application.InputBox("Range :", xTitleId, InputRng.Address, Type:=8)
Set OutRng = Application.InputBox("Out put to (single cell):", xTitleId, Type:=8)
For Each rng In InputRng
If rng.Value <> "" Then
dt(rng.Value) = ""
End If
Next
OutRng.Range("A1").Resize(dt.Count) = Application.WorksheetFunction.Transpose(dt.Keys)
End Sub
``````

3. Then press F5 to run this code, and a prompt box will pop out to remind you select the data range that you want to use. See screenshot:

4. And then click OK, another prompt box will appear to let you choose a place to put the result, see screenshot:

5. Click OK to close this dialog, and all the unique values have been extracted at once.

Thank you for this solution, however what if the columns are in separate excel sheet? or is in separate columns instead of a table?

Hello, Jon,
The methods in this article ar only works well for a range of data, if your data in separate columns, you should copy and paste them into one range first, and then apply the formula or VBA code.
Thank you!

Thank you for this great article.

For people who are using the array formular in non-English Excel there must be taken special care of the text format string: in your example: "R0C00".
For German this would translate to "Z0S00". However, "S" is a special character refering to seconds for time formating. This character needs to be escaped and therefore the correct format string for German Excel is "Z0\S00".

I hope this helps someone in the future :-)

Hello Sir! The VBA worked wonders, thank you very much for that! I was wondering, If I change the original data, is it possible to refresh the column with the unique values automatically?

Hello Ioannis,

Glad to help. After you change the original data, the VBA can not refresh the result automatically. And the easiest way I can think of is to press Ctrl + Alt + F9 to refresh all results in worksheets in all open workbooks. Have a nice day.

Sincerely,
Mandy

The array formula at the top is working great when used with data in the same sheet, however when I try to use it to reference the same exact data from another sheet the formula returns nothing. I'm unable to figure out why. Is there a limitation with array functions that prevents you from referencing ranges in a different sheet?

Thanks for any insight you can provide.

Hello Erin,

Glad to help. The INDIRECT function in this formula is more complicated to use when referencing data in other worksheets. It is not recommended to use this feature when referencing ranges in different worksheets.

For example: Now the data is in Sheet1, I want to reference the content of cell C2 of Sheet1 in Sheet2. First, in any two cells in Sheet2, such as D1 and D2, enter Sheet1 and C2, respectively. At this point, enter the formula in the empty cell of Sheet2:
=INDIRECT("'"&D1&"'!"&D2), then the content of cell C2 in Sheet1 can be returned.

As you can see, it make things way more complex. Hope my explanation can help. Have a nice day.

Sincerely,
Mandy
