Screenshot?
I think he explained it succinctly.

How do I get it to start over at A when Z is used?

@Harold McBroom Everything man does is corrupt. Everything.

Yeah Dan! DAH!
You seem to assume we're all brainiacs like you Dan.
You can't possibly expect us to wrap our heads around what you mean without screenshots! Wow!

This code will allow you to go from A to ZZ.

=IF(B2="Z","AA",IF(LEN(B2)=1,CHAR(CODE(B2)+1),IF(RIGHT(B2,1)="Z",CHAR(CODE(LEFT(B2,1))+1),LEFT(B2,1))&CHAR(65+MOD(CODE(RIGHT(B2,1))+1-65,26))))

@afzalss Hi,
Please select the number cells and run the below code to solve the problem.

Sub NumTOAZ()
Dim xRg As Range
Dim xStr As String
On Error Resume Next
For Each xRg In Selection
xStr = Replace(Cells(1, xRg.Value).Address(False, False), "1", "")
xRg.Value = xStr
Next
End Sub

@Afzal Hi,
Way not keep using the VBA code? The above VBA code can create letters from A to Z then AA to AZ and so on to meet your needs.

Is there a way to do this for entire words? Where every letter in the word moves up by X number of characters

Excel was the spreadsheet that superseded Lotus 1-2-3, and having been around that long, you would think that geniuses at Microsoft would have created a more simple means of retrieving a cells column number, without having to write your own function. Back in 2001, 2002 when I was programming in VBA there were only 65536 rows in an Excel spreadsheet, now the number has increased to a ridiculous 1.4 million rows. It's not how big the database is that counts, but how intelligent you manage the data on your hard drive, when accessing that data through Excel.

If that doesn't make you upset, then the Bankers Rounding scheme used by Excel should finish the job! We were taught math in school, basic rounding, come to find out, the Bankers "guild" wants to determine how cash amounts are rounded to better cater to their advantages. For instance, 1.5 is either closer to 1 or 2, but is rounded up to 2, being the even number. 0.5 is either closer to 0 or 1, but being the odd number, they round it down to 0. The entire system is corrupt, and they create the business software used by American businesses.



I read a comment below the one I'm addressing, and someone basically said, "I have a lot of banker friends, and they never heard of Bankers Rounding; They say they used a method called "5 Step Rounding" in the EU. So does that mean the Bankers Rounding is used only in the sabotage of the American Economy, but not good enough to ruin the European Economy that's trying to take over the world?! These money changers never cease to amaze me at how far they will go in their arrogance!

Dear Sir
When I run the function =ColLtrs(ROW()) in an excel sheet, I get perfect results, but if I want to call this function or cell value in VBA, then is it possible. So my variable could be i with values 1,2,3,4,....27,28, etc and result should be A,B,C,D....,AA,AB and so on. Is it possible?
Thanks

the formula =ColLtrs(ROW()) works perfectly well in an excel cell, I need to use the same inside a VBA to give me result from A to Z then AA to AZ and so on. If I use CHAR in VBA it has limitation to go only till Z.

@cdarzur Found the answer. Thank you.
=LEFT(B1,4)&"_"&CHAR(CODE(RIGHT(B1,1))+1)

thank you for the above. But what if you want to increment from 400_A to 400_B? I tried a few things but I can only make it work with numbers.
Thanks
