Try the following Excel macro:
Sub TallyTableData()
'Note: this code requires a reference to the Word object model.
'See under the VBE's Tools|References.
Application.ScreenUpdating = False
Dim wdApp As New Word.Application, wdDoc As Word.Document, wdRng As Word.Range
Dim strFolder As String, strFile As String
Dim WkSht As Worksheet, r As Long
strFolder = GetFolder: If strFolder = "" Then GoTo ErrExit
Set WkSht = ActiveSheet: r = 1
strFile = Dir(strFolder & "\*.doc", vbNormal)
While strFile <> ""
Set wdDoc = wdApp.Documents.Open(Filename:=strFolder & "\" & strFile, AddToRecentFiles:=False, ReadOnly:=True, Visible:=False)
With wdDoc
If .Tables.Count > 1 Then
Set wdRng = .Tables(2).Range
If r > 1 Then wdRng.Start = wdRng.Tables(1).Rows(2).Range.Start
wdRng.Copy
WkSht.Paste Destination:=WkSht.Range("A" & r)
r = r + wdRng.Rows.Count + 1
End If
.Close SaveChanges:=False
End With
strFile = Dir()
Wend
With WkSht
.UsedRange.Sort Key1:=.Columns("A"), Order1:=xlAscending, Header:=xlNo
For r = .Cells(.Rows.Count, 1).End(xlUp).Row To 2 Step -1
If .Range("A" & r - 1).Value = .Range("A" & r).Value Then
If IsNumeric(.Range("B" & r).Value) Then .Range("B" & r - 1).Value = .Range("B" & r).Value + .Range("B" & r - 1).Value
.Rows(r).EntireRow.Delete
End If
Next
End With
ErrExit:
wdApp.Quit
Set wdRng = Nothing: Set wdDoc = Nothing: Set wdApp = Nothing: Set WkSht = Nothing: Set WkBk = Nothing
Application.ScreenUpdating = True
End Sub
Function GetFolder() As String
Dim oFolder As Object
GetFolder = ""
Set oFolder = CreateObject("Shell.Application").BrowseForFolder(0, "Choose a folder", 0)
If (Not oFolder Is Nothing) Then GetFolder = oFolder.Items.Item.Path
Set oFolder = Nothing
End Function
The macro has a folder browser, so all you need do is select the folder to process.
