Randomizing a list in Excel can be a useful tool for various purposes, such as conducting surveys, generating random samples, or shuffling data. Fortunately, Excel offers several methods to randomize a list, making it easy for users to manipulate data effectively. In this article, we will explore different techniques to randomize a list in Excel.

Using RAND Function
The RAND function is one of the simplest methods to randomize a list in Excel. This function generates a random number between 0 and 1, which can be used to shuffle the order of a list. Follow these steps to randomize a list using the RAND function:
- Select the cells that contain the list you want to randomize.
- In an empty cell, enter the formula =RAND() and press Enter.
- Drag the fill handle of the cell containing the RAND formula down to cover the entire list.
- Select the entire list, including the column with the RAND values.
- Go to the Data tab, click Sort, and choose Custom Sort.
- In the Sort dialog box, select the column with the RAND values in the Sort by dropdown menu and click OK.
- Your list will now be randomized based on the random numbers generated by the RAND function.
Using RANDBETWEEN Function
If you want more control over the range of random numbers, you can use the RANDBETWEEN function in Excel. This function allows you to specify a range within which random numbers will be generated. Here’s how to randomize a list using the RANDBETWEEN function:
- Select the cells that contain the list you want to randomize.
- In an empty cell, enter the formula =RANDBETWEEN(1,1000) and press Enter.
- Drag the fill handle of the cell containing the RANDBETWEEN formula down to cover the entire list.
- Select the entire list, including the column with the RANDBETWEEN values.
- Go to the Data tab, click Sort, and choose Custom Sort.
- In the Sort dialog box, select the column with the RANDBETWEEN values in the Sort by dropdown menu and click OK.
- Your list will now be randomized based on the random numbers generated by the RANDBETWEEN function within the specified range.
Using VBA Macro
Excel’s Visual Basic for Applications (VBA) allows you to automate tasks and create custom functions, making it a powerful tool for randomizing lists. If you are comfortable with programming, you can use a VBA macro to shuffle the order of a list in Excel. Follow these steps to randomize a list using a VBA macro:
- Press Alt + F11 to open the Visual Basic Editor.
- Go to Insert and select Module to create a new module.
- Paste the following VBA code into the module:
Sub RandomizeList()
Dim i As Long, j As Long
Dim rng As Range
Set rng = Selection
With Application
.ScreenUpdating = False
For i = rng.Rows.Count To 2 Step -1
j = .RandBetween(1, i)
rng.Cells(j).Cut
rng.Cells(i).Insert Shift:=xlDown
Next i
.CutCopyMode = False
.ScreenUpdating = True
End With
End Sub
- Press Ctrl + S to save the macro.
- Close the Visual Basic Editor.
- Select the cells that contain the list you want to randomize.
- Press Alt + F8, select RandomizeList, and click Run.
- Your list will now be randomized using the VBA macro.
Using Excel Add-Ins
If you prefer a user-friendly interface for randomizing lists in Excel, you can install Excel add-ins that offer specialized tools for data manipulation. Add-ins such as ASAP Utilities and Kutools for Excel provide features that include shuffling data, randomizing lists, and more. Here’s how you can use Excel add-ins to randomize a list:
- Download and install the Excel add-in of your choice.
- Open Excel and navigate to the Add-Ins tab.
- Click on the add-in menu and select the randomize or shuffle option.
- Follow the on-screen instructions to randomize your list.
- Enjoy the convenience of using add-ins for list randomization in Excel.
Things to Consider
When randomizing a list in Excel, there are a few important considerations to keep in mind:
- Data Integrity: Randomizing a list can alter the original order of data, so make sure to create a backup of your list before proceeding.
- Duplicates: Depending on the method used, duplicates may occur when shuffling a list. Check for duplicates and adjust your randomization technique if necessary.
- Sorting: After randomizing a list, you may want to sort the data back to its original order. Use Excel’s sort feature to rearrange the list if needed.
By following these considerations and using the methods outlined in this article, you can effectively randomize a list in Excel for various applications. Whether you choose to utilize functions, macros, or add-ins, Excel provides the tools you need to manipulate data with ease.
