This solution works for spreadsheets without empty cells.

To handle empty cells, you will need to replace this line:

tempRow[i] = GetCellValue(spreadSheetDocument, row.Descendants().ElementAt(i-1));

with something like this:

Cell cell = row.Descendants().ElementAt(i);
int index = CellReferenceToIndex(cell);
tempRow[index] = GetCellValue(spreadSheetDocument, cell);

And add this method:

private static int CellReferenceToIndex(Cell cell)
{
    int index = -1;
    string reference = cell.CellReference.ToString().ToUpper();
    foreach (char ch in reference)
    {
        if (Char.IsLetter(ch))
        {
            int value = (int)ch - (int)'A';
            index = (index + 1) * 26 + value;
        }
        else
            return index;
    }
    return index;
}
