Note that in the case of AA the first A has a value of 26 times the second i.e. You can use that reference to extract the column number.Īs you probably know, in Excel A = 1, B = 2 etc up to Z = 26 at which point the cells are prefixed with A to give AA = 27, AB = 28 etc. To get the index you can use the Cell object wihch has a CellReference property that gives the reference in the format A1, B1 etc. This is slightly trickier than you might imagine because the schema allows for empty cells to be omitted. ![]()
