Answer 1

Just an improvement, the col-- was in the wrong place

static string GetCellAddress(int row, int col)
    {
        StringBuilder sb = new StringBuilder();

       do
        {
            col--;
            sb.Insert(0, (char)('A' + (col % 26)));
            col /= 26;
        } while (col > 0);
        sb.Append(row);
        return sb.ToString();
    }
