Generating Unique, Sequential Names

Steven is testing some software and he needs to feed into the program a bunch of "fake" names. He would like these names to be patterned such as Nameaaa, Nameaab, Nameaac, and so on through Namezzz. This would require creating 17,576 names (26 x 26 x 26). He wonders if there is an easy way to generate all these names in Excel.

This sort of repetitive task just cries out for a macro. (They are great for doing boring, dull, repetitive tasks that you don't want to do manually.) Listing 1 shows a simple macro that can do the required grunt work.

Listing 1. CreateNames macro. 
Sub CreateNames()
    Dim i As Integer
    Dim x As Integer
    Dim y As Integer
    Dim z As Integer

    i = 1
    For x = 97 To 122
        For y = 97 To 122
          For z = 97 To 122
              Cells(i, 1) = "Name" & Chr(x) _
                & Chr(y) & Chr(z)
              i = i + 1
            Next
        Next
    Next
End Sub

The macro uses three variables (x, y, and z) to serve as "counters" that control which letter of the alphabet is appended to the "name" stuffed into a cell. Notice that the For ... Next loops range from 97 to 122, which are the ASCII codes for lowercase a through z.

If you don't want to use a macro for some reason, type the following formula into cell A1 of a blank worksheet:

="Name" & CHAR((ROW()-1)/676+97)&CHAR(MOD(
(ROW()-1)/26,26)+97)&CHAR(MOD(ROW()-1,26)+97)

This is a single formula, and it results in "Nameaaa" being displayed. Copy the formula down through row 17,576 and you'll have your fake names.

For people with Excel 365, this slight modification of Allen's formula will also work. The benefit is it doesn't require filling down.

=LET(index,SEQUENCE(26*26*26)-1,"Name"&CHAR(index/676+97)&CHAR(MOD(index/26,26)+97)&CHAR(MOD(index,26)+97))
