Select the cell in which you want to get the random numbers. In the active cell, enter =RANDBETWEEN(1,100). Hold the Control key and Press Enter.

Give this a shot.

<%= [*5..30].sample %>

<%= rand(5..30) %>

This would generate a random number in that range:

5 + rand(25)

Simply add the min to the rand(max-min).
