# Alphabetic Column Designation by Allen Wyatt
(last updated September 4, 2019)

You can easily determine the numeric column of cell by using the COLUMN function. All you need to do is put a formula like this in a cell, and the result is a value where A=1, B=2, etc.:

```=COLUMN()
```

What if you want an alphabetic value, rather than a numeric value? This can be done in any of several different ways. For instance, the following formula will work very nicely for the first 26 columns, A through Z:

```=CHAR(COLUMN()+64)
```

This works because the letters A through Z use character codes 65 through 90. When COLUMN returns a value for columns A through Z (1 through 26), this can be added to 64 to get the letters of those columns, 65 through 90.

Of course, this solution won't work if you want to know the letter designations of columns beyond Z. (Excel can use columns up through IV.) This formula will work for single- and double-character columns:

```=IF(COLUMN()<27,CHAR(COLUMN()+64),CHAR((COLUMN()/26)+64)&
CHAR(MOD(COLUMN(),26)+64))
```

As you can tell, when you get into multiple characters for a column, the formula gets long rather quickly. You can make the formula shorter by using a function other than COLUMN, however. Consider this formula, which relies primarily upon the ADDRESS function:

```=LEFT(ADDRESS(1,COLUMN(),4),(COLUMN()>26)+1)
```

The ADDRESS function returns the address of a specific cell. In this case, it returns the address for the cell in the first row of the current column. Thus, if the formula is in cell BF27, it returns BF1. The formula uses the LEFT function to return the correct number of left-most characters in the address, minus the number 1 for the row.

An even shorter version of the formula relies upon the SUBSTITUTE function instead of the LEFT function:

```=SUBSTITUTE(ADDRESS(ROW(),COLUMN(),4),ROW(),"")
```

This version uses the ROW function to put the address together, and then strips the ROW value out of the result of the ADDRESS function.

Of course, you can also use a macro-based solution, if you want to. The follow macro will work with any column in your worksheet:

```Function AlphaCol() As String
Dim J As Integer
Dim K As Integer
Dim iDiv As Integer
Dim sTemp As String

Application.Volatile
J = Selection.Column
iDiv = 26 ^ 2
sTemp = ""
While J > 0
K = Int(J / iDiv)
If K > 0 Then sTemp = sTemp & Chr(K + 64)
J = J - (K * iDiv)
iDiv = iDiv / 26
Wend
AlphaCol = sTemp
End Function
```

The macro is a user-defined function, which means that you can use it in your worksheets by simply adding this to any cell:

```=AlphaCol()
```

A text string is returned, consisting of the column designation.

This tip's macro is really making a mountain out of a molehill. Here is a one-iner that does the job equally well:

Function AlphaCol() As String
End Function
