How to randomize a list in Excel with a formula
Although there is no native function to perform random sort in Excel, there is a function to generate random numbers (Excel RAND function) and we are going to use it.
Assuming you have a list of names in column A, please follow these steps to randomize your list:
Insert a new column next to the list of names you want to randomize. If your dataset consists of a single column, skip this step.
In the first cell of the inserted column, enter the RAND formula: =RAND()
Copy the formula down the column. The fastest way to do this is by double-clicking the fill handle:

Sort the column filled with random numbers in ascending order (descending sort would move the column headers at the bottom of the table, you definitely don't want this). So, select any number in column B, go to the Home tab > Editing group and click Sort & Filter > Sort Largest to Smallest.

Or, you can go to the Data tab > Sort & Filter group, and click the ZA button .
Either way, Excel automatically expands the selection and sorts the names in column A as well:

Tips & notes:
Excel RAND is a volatile function, meaning that new random numbers are generated every time the worksheet is recalculated. So, if you are not happy with how your list has been randomized, keep hitting the sort button until you get the desired result.
To prevent the random numbers from recalculating with every change you make to the worksheet, copy the random numbers, and then paste them as values by using the Paste Special feature. Or, simply delete the column with the RAND formula if you don't need it any longer.
