I did a google search and found some relevant code by Andy Pope which works in Word to read or write to its own embedded spreadsheet.
Code:
Sub WriteToSS()

' added a couple of lines to read cell values and save any changes
Dim objSS As InlineShape
With ActiveDocument.InlineShapes(1)
.OLEFormat.DoVerb wdOLEVerbHide
With .OLEFormat.Object.Application
With .Workbooks(1).Worksheets(1)
Debug.Print .Cells(1, 1).Value, .Range("B1").Value 'reading cells
.Cells(1, 1).Value = "Hello" 'writing to a cell
.Range("B1").Value = "Big Boy" 'writing to another cell
End With
.Workbooks(1).Save 'if you wanted to save the changed cell values
.Quit
End With
End With
End Sub
If you are already running code from Excel to access that Word document then you've got that part of the automation running and can adapt the relevant lines above into your existing code.
Getting the right InlineShape might be a bit tricky and relying on its numerical position in the document is problematic so I would probably use Format Object to set its Alt Text to a unique value so the code could iterate through all the InlineShapes to find the one which has that Alt Text value. An example of looping through a docs Shapes (same for InlineShapes) is shown in
this thread.
