Home PWGen is a professional password generator capable of generating large amounts of cryptographically-secure passwords— “classical” passwords, pronounceable passwords, pattern-based passwords, and passphrases consisting of words from word lists. It uses a “random pool” technique based on strong cryptography to generate random data from indeterministic user inputs (keystrokes, mouse handling) and volatile system parameters. PWGen provides lots of options to customize passwords to the users’ various needs. Additionally, it offers strong text encryption and the creation of random data files (which can be used as key files for encryption utilities, for example).

The following formulas can help you generate random numbers, letters and alphanumeric values in a range in Excel. To create a random 5-digit number between 10000 and 99999, use this formula: =RANDBETWEEN(9), and press Enter key, a 5-digit number will be display in a cell, then select the cell and drag the fill handle across to the range that you want to contain this formula, a range of 5-digit numbers have been generated, see screenshots: Note: you can change the arguments to get your need.

A super easy way to generate lists of random passwords.

To create a random letter, use the this formula: =CHAR(RANDBETWEEN(65,90)). This formula can generate a random letter from a to z, if you need to create four random letters, you need to use & character to add the letters. Such as =CHAR(RANDBETWEEN(65,90))& CHAR(RANDBETWEEN(65,90)) & CHAR(RANDBETWEEN(65,90)) & CHAR(RANDBETWEEN(65,90)). Then you will get a four random letters, and then drag the fill handle over to the range that you want to contain this formula.

See screenshot: Notes: (1.)The formula is valid in Excel 2007, 2010, and 2013, but not Excel 2003. In Excel 2003, please use the formula =CHAR(INT(RAND()* 25 + 65)) & CHAR(INT(RAND()* 25 + 65)) & CHAR(INT(RAND()* 25 + 65)) & CHAR(INT(RAND()* 25 + 65)) (2.) In formula 65 is A and 90 is Z. (3.) You can use the character & to add the number of letters you need. To create a random alphanumeric string that has two letters and two numbers, use this formula: =CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(65,90))&RANDBETWEEN(10,99) And you will get the following strings in a range which contain two letters and two numbers: Note: you can change the arguments to get the digit number as you need, and use & to add the number of letters. Generate random character strings with VBA code If you feel above formulas are difficult and troublesome, the following VBA code can help you much easier. Please do as this: 1. Hold down the ALT + F11 keys, and it opens the Microsoft Visual Basic for Applications window.

Click Insert >Module, and paste the following macro in the Module window. Public Function RandomizeF(Num1 As Integer, Num2 As Integer) 'Update 20131107 Dim Rand As String Application.Volatile getLen = Int((Num2 + 1 - Num1) * Rnd + Num1) Do i = i + 1 Randomize Rand = Rand & Chr(Int((85) * Rnd + 38)) Loop Until i = getLen RandomizeF = Rand End Function 3. Then save and close the code, in a cell, enter this function =RandomizeF(x,y) to insert a random character string with a minimum length of x characters, and a maximum length of y characters. In this example, I will use function =RandomizeF(5,10) to generate a character string which between 5 and 10 characters.

Then press Enter key, select the cell and drag the fill handle to the range you want to contain this function. And random of alphanumeric and specific character strings which between 5 and 10 characters have been created.
