How to list or generate all possible combinations in Excel?
Let’s say, I have the following two columns of data, and now, I want to generate a list of all possible combinations based on the two lists of values as left screenshot shown. Maybe, you can list all the combinations one by one if there are few values, but, if there are several columns with multiple values needed to be listed the possible combinations, here are some quick tricks may help you to deal with this problem in Excel.
The following long formula can help you to list all possible combinations of two lists values quickly, please do as follows:
1. Enter or copy the below formula into a blank cell, in this case, I will enter it to cell D2, and then press Enter key to get the result, see screenshot:
2. Then select cell D2 and drag the fill handle down to the cells until get the blank cells, and all the possible combinations have been listed based on the two lists values. See screenshot:
Maybe the above formula is somewhat difficult for you to apply, if there are multiple columns data, it will be troublesome for modifying. Here, I will introduce a VBA code to deal with it quickly.
1. Hold down the ALT + F11 keys to open the Microsoft Visual Basic for Applications window.
2. Click Insert > Module, and paste the following code in the Module Window.
VBA code: Generate all combinations of 3 or multiple columns
Sub ListAllCombinations() 'Updateby Extendoffice Dim xDRg1, xDRg2, xDRg3 As Range Dim xRg As Range Dim xStr As String Dim xFN1, xFN2, xFN3 As Integer Dim xSV1, xSV2, xSV3 As String Set xDRg1 = Range("A2:A5") 'First column data Set xDRg2 = Range("B2:B4") 'Second column data Set xDRg3 = Range("C2:C4") 'Third column data xStr = "-" 'Separator Set xRg = Range("E2") 'Output cell For xFN1 = 1 To xDRg1.Count xSV1 = xDRg1.Item(xFN1).Text For xFN2 = 1 To xDRg2.Count xSV2 = xDRg2.Item(xFN2).Text For xFN3 = 1 To xDRg3.Count xSV3 = xDRg3.Item(xFN3).Text xRg.Value = xSV1 & xStr & xSV2 & xStr & xSV3 Set xRg = xRg.Offset(1, 0) Next Next Next End Sub
3. Then, press F5 key to run this code, and all combinations of the 3 columns will be generated at once, see screenshot:
If there are multiple lists values need to be listed the possible combinations, maybe it is difficult for you to modify the code. Here, I can recommend a powerful tool -- Kutools for Excel, it contains a handy feature List All Combinations which can quickly list all the possible combinations based on given data lists.
After installing Kutools for Excel, please do as this:
1. Click Kutools > Insert > List All Combinations, see screenshot:
2. In the List All Combinations dialog box, do the operations as below demo shown:
3. Then all the specified values and separators have been listed into the dialog box, see screenshot:
4.And then click Ok button, and a prompt box will pop out to remind you select a cell to output the result, see screenshot:
5. Click OK, all of the possible combinations based on the given lists have been generated into the worksheet as following screenshot shown:
