Using either the original document or a document answered as it should be as a base, you can use Word's document comparison tool to identify any differences between it and the submitted one. The following macro will expedite the process. Simply add the macro to the base document, then run the macro. All you need do is select the folder containing the files to be marked. The output files (with the 'Marked' suffix) will mark any differences between the base document and the comparison documents as tracked changes.
Sub MarkDocuments()
Application.ScreenUpdating = False
Dim strFolder As String, strFile As String, strDocNm As String, wdDoc As Document
Set wdDoc = ActiveDocument: strDocNm = wdDoc.FullName
strFolder = GetFolder
If strFolder = "" Then Exit Sub
strFile = Dir(strFolder & "\*.doc", vbNormal)
Do While strFile <> ""
If strFolder & "" & strFile <> strDocNm Then
wdDoc.Merge FileName:=strFolder & "" & strFile, MergeTarget:=wdMergeTargetNew, _
DetectFormatChanges:=True, UseFormattingFrom:=wdFormattingFromCurrent, AddToRecentFiles:=False
With ActiveDocument
.SaveAs FileName:=strFolder & "" & Split(strFile, ".doc")(0) & " - Marked.docx", _
FileFormat:=wdFormatXMLDocument, AddToRecentFiles:=False
.Close False
End With
End If
strFile = Dir()
Loop
Set wdDoc = 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
