You can use the Interop dll's from Microsoft to edit office documents http://msdn.microsoft.com/en-us/library/15s06t57.aspx. Add the "Microsoft.Office.Interop.Excel.dll" to your solution. With this code i've changed 2 cell values.

static void Main(string[] args)
{
        Application excel = new Application();

        Workbook workbook = excel.Workbooks.Open(@"C:\Users\Martijn\Documents\Test.xlsx", ReadOnly: false, Editable:true);
        Worksheet worksheet = workbook.Worksheets.Item[1] as Worksheet;
        if (worksheet == null)
            return;

        Range row1 = worksheet.Rows.Cells[1, 1];
        Range row2 = worksheet.Rows.Cells[2, 1];

        row1.Value = "Test100";
        row2.Value = "Test200";


        excel.Application.ActiveWorkbook.Save();
        excel.Application.Quit();
        excel.Quit();
    }

I've started with Test1 and Test2 wich after the program running changed into the proper values.
