Word – Split Word/PDF files into multiple documents

This is easy to do in Word 2007 and 2010. You don't need any third party tools.

In Word 2007, you need the Microsoft PDF Add-In to allow you to save as PDF. Download it from here. In Word 2010 the Add-In is unnecessary.

1. Open your document
2. Mark the headings you want using the standard Heading 1, Heading 2, etc. styles. You can create a table of contents too, but you don't have to.
3. Select Save As > PDF
4. The first time you do this you have to set an option
   • Click Options
   • Check the Create Bookmarks using headings check box.
   • Click OK
5. Click Publish

EDIT:

Use this Macro, it will throw an error, if you have no open document:

Sub OpenMultipleFiles()
Dim fDialog As FileDialog

Set fDialog = Application.FileDialog(msoFileDialogFilePicker)
With fDialog
.AllowMultiSelect = True
.InitialView = msoFileDialogViewList
If .Show <> -1 Then
MsgBox "Cancelled By User", , "Cancelled"
Exit Sub
End If
End With
For i = 1 To fDialog.SelectedItems.Count
Selection.InsertFile fDialog.SelectedItems.Item(i)
Selection.InsertBreak Type:=wdPageBreak

Next i
End Sub

While in Word press ALT+F11 this brings up the VBA Editor. Afterwards expand Normal to see the Modul folder. If it does not exist click on Normal -> Insert -> Modul Paste the Macro and save.

Afterwards you can add a button with the macro to your toolbars.
