There are sites where you can upload lists and pick a random winner, but it's probably best not to upload information to random sites. Here's how you can do it in Excel:
- Click on the uppermost cell of your list after the final column of actual information
- In the formula bar, type: =RAND()
- That will generate a random number in the cell, like 0.57450713
- Double click the lower right corner of that cell to run the random list of numbers all the way down the column.
- Sort the sheet based on that column.
What it does, is assign a random number to each row, then you sort, putting those random numbers in order, but mixing up everything else. BOOM! Just pick the new first X number of rows as your winners --- totally random!
