This post will guide you how to generate random numbers between two numbers in Excel. How do I generate random numbers between two numbers without duplicates with VBA macro in Excel.

1. Generate Random Numbers between Two Numbers with Formula

If you want to generate random numbers between two given numbers, you can use a formula based on the RANDBETWEEEN function in Excel.

For example, you need to generate random numbers between 10 and 100 numbers, you can use the following formula:

=RANDBETWEEN(10,100)

Type this formula into a blank cell, and press Enter key on your keyboard, and then drag the AutoFill handle to other cells to generate more random numbers.

If you want to generate random number between 0 and 1, you can directly use the RAND function. Like this:

=RAND()

2. Generate Random Numbers between Two Numbers with VBA

You can also use VBA code to define a new function to achieve the same result of generating random numbers with 2 decimal places between two given numbers in Excel. Or you can generate random numbers with given decimal places in a given range of cells in Excel. Here are the steps:

#1 open your excel workbook and then click on “Visual Basic” command under DEVELOPER Tab, or just press “ALT+F11” shortcut.

#2 then the “Visual Basic Editor” window will appear.

#3 click “Insert” ->”Module” to create a new module.

#4 paste the below VBA code into the code window. Then clicking “Save” button.

Public Function RandomRealNumbers(lowNum As Long, highNum As Long, _
Optional decN As Integer)
   If IsMissing(decN) Or decN = 0 Then
      Randomize
      RandomRealNumbers= Int((highNum + 1 - lowNum) * Rnd + lowNum)
   Else
      Randomize
      RandomRealNumbers= Round((highNum - lowNum) * Rnd + lowNum, decN)
   End If
End Function

#5 back to the current worksheet, then type the following formula in a blank cell, and then press Enter key.

=RandomRealNumbers(10,100,2)

#6 drag the AutoFill handle over other cells to  generate random numbers with two decimal places between two given numbers 10 and 100.
