The following macro copies text one page at a time and then saves that text in a new document. The macro uses the pre-defined bookmark "\page" and the document's built-in property of "number of pages".

split-file macro

The following macros show how to break up a multi-page document into separate files. The two macros use the Page or Section property of a Microsoft Word document to select and move through the document content. This code can be used in an automation scenario with Word not visible.

Separate File by Page

Sub BreakOnPage()
   ' Used to set criteria for moving through the document by page.
   Application.Browser.Target = wdBrowsePage

   For i = 1 To ActiveDocument.BuiltInDocumentProperties("Number of Pages")
      
      'Select and copy the text to the clipboard
      ActiveDocument.Bookmarks("\page").Range.Copy

      ' Open new document to paste the content of the clipboard into.
      Documents.Add
      Selection.Paste

      ' Removes the break that is copied at the end of the page, if any.
      Selection.TypeBackspace
      ChangeFileOpenDirectory "C:\"
      DocNum = DocNum + 1
      ActiveDocument.SaveAs FileName:="test_" & DocNum & ".doc"
      ActiveDocument.Close

      ' Move the selection to the next page  in the document
      Application.Browser.Next
   Next i
   ActiveDocument.Close savechanges:=wdDoNotSaveChanges
End Sub
				

Separate File by Section

The following macro copies text one section at a time and then saves that text in a new document. The macro uses the pre-defined bookmark "\section" to create the new document. This macro is useful for breaking up a mail merge "Merge to New Document" file.


Sub BreakOnSection()
   ' Used to set criteria for moving through the document by section.
   Application.Browser.Target = wdBrowseSection

   'A mailmerge document ends with a section break next page.
   'Subtracting one from the section count stop error message.
   For i = 1 To ((ActiveDocument.Sections.Count) - 1)
   
      'Select and copy the section text to the clipboard
      ActiveDocument.Bookmarks("\Section").Range.Copy

      'Create a new document to paste text from clipboard.
      Documents.Add
      Selection.Paste

   ' Removes the break that is copied at the end of the section, if any.
      Selection.MoveUp Unit:=wdLine, Count:=1, Extend:=wdExtend
      Selection.Delete Unit:=wdCharacter, Count:=1

     ChangeFileOpenDirectory "C:\"
      DocNum = DocNum + 1
     ActiveDocument.SaveAs FileName:="test_" & DocNum & ".doc"
     ActiveDocument.Close
      ' Move the selection to the next section in the document
     Application.Browser.Next
   Next i
   ActiveDocument.Close savechanges:=wdDoNotSaveChanges
End Sub
				


NOTE: When this code is used to select and copy the text content of the document, the header and footer are not retained. Styles, fonts, and layout may change if the main file and the new document are from different templates, but direct formatting is maintained.
