Now, we want only values in the Random Number column.

➤ After that, we click on Copy.
Now, we will paste the copied number into the same cells.
➤ We will select from cell D3 to D12, and we will right-click on the mouse.
➤ After that, we will click on Paste Special and then click on Paste Values.
Now, we can see in the Random Number column that there is no formula in the formula bar.
Therefore, there are only values in the Random Number column.
➤ Now, we will select our entire dataset, and we will go to the Home tab.

In this method, we want to select a single random name.
We will use the INDEX, RANDBETWEEN, and ROWS functions.
➤ First of all, we will type the following function in cell E3.
=INDEX($B$3:$B$17,RANDBETWEEN(1,ROWS($B$3:$B$17)))Here,
- ROWS($B$3:$B$17)→ Returns number of rows between cells B3 to B17.
- RANDBETWEEN(1,ROWS($B$3:$B$17))→ Returns a random number between 1 and number of rows.
- INDEX($B$3:$B$12, RANK(D3,$D$3:$D$12), 1)→ The number returned by RANDBETWEEN is fed to the row_num argument of the INDEX function, so it picks the value from that row. In the column_num argument, we supply 1 because we want to extract a value from the first column.
➤ Now, press ENTER.
We can see a random name Robb in our Single Random Name column.

- RAND()→Returns column D with random numbers.
- RANK(D3,$D$3:$D$12)→ Returns the rank of a random number in the same row. For example, RANK(D3,$D$3:$D$12) in cell E3 gets the rank of the number in D3. When copied to D4, the relative reference D3 changes to D4 and returns the rank of the number in D4, and so on.
- INDEX($B$3:$B$12, RANK(D3,$D$3:$D$12), 1)→The number returned by RANK is fed to the row_num argument of the INDEX function, so it picks the value from that row. In the column_num argument, we supply 1 because we want to extract a value from the first column.
➤ Press ENTER.
