This tip applies to Excel 2007, 2010, 2013, 2016, 2019, Excel in Microsoft 365, and 2021
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))
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
