Get Excel-Style Column Names from Column Number

Question

This is the code for providing the COLUMN name when the row and col ID is provided but when I give values like row = 1 and col = 104, it should return CZ<

Answer 1

You have a couple of index issues:

So to fix your problem, you need to make all your indices match:

def colToExcel(col): # col is 1 based
    excelCol = str()
    div = col 
    while div:
        (div, mod) = divmod(div-1, 26) # will return (x, 0 .. 25)
        excelCol = chr(mod + 65) + excelCol

    return excelCol

print colToExcel(1) # => A
print colToExcel(26) # => Z
print colToExcel(27) # => AA
print colToExcel(104) # => CZ
print colToExcel(26**3+26**2+26) # => ZZZ
