I have a word file that should be embedded in excel file. I can put a word file, but it only shows as .bin file inside excel zipped file. How can I make it visible inside excel (let's say at position cell C3)? I also need to edit that embeded word file later. Interop is not an answer, because this project should work on a server machine. Thank you. So far i tried something like this.

public static void addWordFile(string fileName, string tableDoc)
{
    using (SpreadsheetDocument  document = SpreadsheetDocument.Open(fileName, true))
    {

        WorkbookPart wbPart = document.WorkbookPart;


        // Find the sheet with the supplied name, and then use that 
        // Sheet object to retrieve a reference to the first worksheet.
        Sheet theSheet = wbPart.Workbook.Descendants<Sheet>().
          Where(s => s.Name == "Test4").FirstOrDefault();

        // Throw an exception if there is no sheet.
        if (theSheet == null)
        {
            throw new ArgumentException("sheetName");
        }

        // Retrieve a reference to the worksheet part.
        WorksheetPart wsPart =
            (WorksheetPart)(wbPart.GetPartById(theSheet.Id));



        EmbeddedPackagePart newEmbeddedPackagePart = wsPart.AddNewPart<EmbeddedPackagePart>(@"application/vnd.openxmlformats-officedocument.wordprocessingml.document", "rId100");
        newEmbeddedPackagePart.FeedData(File.Open(@tableDoc, FileMode.Open));
      

    }
}
