## How to insert random (integer) numbers between two numbers without repeats in Excel?

Do you need to insert random numbers in Microsoft Excel? There are several methods to insert random numbers in a range as follows:

Insert random numbers by formulas

Insert random numbers with specified decimal places by VBA

### Randomly insert whole numbers / dates / time between two numbers/dates/times without repeats

Kutools for Excel's Insert Random Data utility enables to insert random integers (whole numbers) between two certain numbers easily, randomly insert a series of dates (only workdays, or only weekends, or no limitation) between two dates, randomly insert a series times between two times, or generate random text strings with certain length. And the Unique values option will prevent from inserting duplicates.

#### Insert random numbers between two numbers with RAND function and RANDBETWEEN formulas

This method will apply the RAND function and RANDBETWEEN function to insert random numbers between two numbers into a specified range in Excel. Please view below formulas:

 Formula Description (Result) =RAND() A random number between 0 and 1 (varies) =RAND()*100 A random number between 0 and 100 (varies) =RANDBETWEEN(low, high) A random integral number between two given integer numbers, such as RANDBETWEEN(50, 100).

See below screenshots:

 Random numbers between 0 and 1 =RAND() Random numbers between 0 and 100 =RAND()*100 Random integer numbers between 50 and 100 =RANDBETWEEN(50, 100)

#### Insert random numbers between two numbers with specified decimal places by VBA

Below VBA can help you insert any random integer numbers or random numbers with given decimal places into a specified range in Excel. Please do as follows:

1. Hold down the ALT + F11 keys, and it opens the Microsoft Visual Basic for Applications window.

2. Click Insert > Module, and paste the following code in the Module window.

``````Public Function RandomNumbers(Num1 As Long, Num2 As Long, Optional Decimals As Integer)
'Update20131113
Application.Volatile
Randomize
If IsMissing(Decimals) Or Decimals = 0 Then
RandomNumbers = Int((Num2 + 1 - Num1) * Rnd + Num1)
Else
RandomNumbers = Round((Num2 - Num1) * Rnd + Num1, Decimals)
End If
End Function
``````

3. Save and close the code, then in a blank cell, input this formula =RandomNumbers(X,Y,Z), X indicates the lower limit of the numbers, Y indicates the higher limit of the numbers, and Z is the specified decimal places of random numbers.

For example, I want to generate some whole numbers between 50 and 1000, I can insert this formula =randomnumbers (50,1000,0); and insert random numbers between 50 and 100 with 2 decimal places with this formula =randomnumbers (50,100,2). See below screenshots:

5. Try to accomplish the following with your prior knowledge of basic Excel programming. [6] 5.1 Letâ€™s say youâ€™re interested in studying student attitudes toward climate change. If you wanted to randomly sample 50 students out of 643 at a local school, you would need to begin by creating a numbered list of all 643 students (student =1; student =2, student =3 and so forth). Then all you would need to do is to generate a set of random numbers with a range from 1 to 643. Use Excel to accomplish this task. Arrange your list from smallest to largest number. 5.2 Although people sometimes confuse random assignment with random sampling, the two are really quite different. With random sampling, the goal is to choose a representative set of cases from the full population under consideration. With random assignment, the goal is usually to give all participants and equal chance of being assigned to each experimental condition (regardless of how representative the participants are).

Wow, cool, just what I was looking for. Seems Excel 2010 is kind of lame when it comes to options for random numbers.
