Sometimes you may have to generate automatically different random passwords. This could be a very easy task if you just had an Excel function like “RandomPassword”, so you could write:
And get something like:
Well, this is exactly the idea of the Add-In I’ve made…
If this isn’t what you’re looking for, as an alternative, you can visit the online random password generator.
The function syntax is as follows:
=RandomPassword(length, [uppercase = TRUE], [numbers = TRUE], [lowercase = TRUE])
Just as simple as that… Here are the download links:
If you don’t know how you should install an Excel Add-in, keep looking into the site since I’ll write a post about that soon… By now, I can give you this guidelines:
1- Copy the corresponding version of the add-in (XLA or XLAM) to C:\Program Files\Microsoft Office\OfficeXX\Library (where XX is the Office version, being 12 for Office 2007)
2- Follow the instructions given here for Office 2003 or below, or take a look at the first part of this steps for Office 2007.

Just in case you want to see the function code without looking into the add-in:
Function RandomPassword(Length As Integer, Optional Upper As Boolean = True, Optional Number As Boolean = True, Optional Lower As Boolean = True) If Not Upper And Not Lower And Not Number Then RandomPassword = ""; Exit Function End If Dim Ret As String Dim Num As Integer Dim Repeat As Boolean Randomize Chars = 26 * 2 + 10 '26 (a-z) + 26 (A-Z) + 10 (0-9) 'a-z = 97-122 'A-Z = 65-90 '0-9 = 48-57 For i = 1 To Length Repeat = False Num = Int(Chars * Rnd) 'Int((upperbound - lowerbound + 1) * Rnd + lowerbound) If Num &lt; 26 Then 'a-z If Lower Then Ret = Ret & Chr(Num + 97) Else Repeat = True End If ElseIf Num < 52 Then 'A-Z If Upper Then Ret = Ret & Chr(Num - 26 + 65) Else Repeat = True End If ElseIf Num < 62 Then '0-9 If Number Then Ret = Ret & Chr(Num - 52 + 48) Else Repeat = True End If End If If Repeat Then i = i - 1 End If Next i RandomPassword = Ret End Function
