Hi,

Could anyone help me with a macro or formula that could list every three letter combination from AAA to ZZZ in column A of a workbook? Just the logic would be fine as I'm starting to think that the way I've thought of doing it is over complicating it.

Thank you.

How to total the visible cells?
From the first blank cell below a filtered data set, press Alt+=. Instead of SUM, you will get SUBTOTAL(9,)
One idea

Code:
Sub List_Combos()
Dim a As Integer, b As Integer, c As Integer
Dim lst As Long
'65 to 90
For a = 65 To 90
    For b = 65 To 90
        For c = 65 To 90
            lst = Sheet1.Range("A" & Rows.Count).End(xlUp).Row + 1
            Sheet1.Range("A" & lst).Value = Chr(a) & Chr(b) & Chr(c)
        Next c
    Next b
Next a


End Sub

Try this.
Code:
Option Explicit
 
Sub Combos()
Dim I As Long, J As Long, K As Long
Dim s As String
Dim rng As Range
 
    Set rng = Range("A1")

    For I = 1 To 26
        For J = 1 To 26
            For K = 1 To 26
                s = Chr(Asc("A") + I - 1) & Chr(Asc("A") + J - 1) & Chr(Asc("A") + K - 1)
                rng.Value = s
                Set rng = rng.Offset(1)
            Next
        Next
    Next
    
End Sub

Hi

A formula solution for the permutations in columns A:C

In A1:

=IF(ROWS(A$1:A1)>17576,"",CHAR(65+MOD((ROWS(A$1:A1)-1)/26^(3-COLUMNS($A1:A1)),26)))

Copy down and to the right.

pgc beat me to it with the formula version but may as well post my single column effort

=IF(ROW(A1)<=(26^3),CHAR(65+INT((ROW(A1)-1)/26^2))&CHAR(65+MOD(INT((ROW(A1)-1)/26),26))&CHAR(65+MOD(ROW(A1)-1,26)),"")

Cheers guys! Beats my solution of first putting A to Z in an array and then using the array in some loops.
