Merging to Individual Files

When you use the mail-merge feature in Word, you have the option of either printing your results directly or creating a new document. If you choose the latter option, the resulting document contains all the information that normally would have gone to the printer. For instance, if your merge document is a two-page letter, each letter in the resulting document is separated by a section break. Thus, if you are merging the two-page letter with 150 different addresses, then you would end up with a 300-page document with 150 section breaks (one every two pages).

For some people, it would be more helpful if you could merge to individual files. For instance, given the above example you might want 150 individual document files, each two pages long. Unfortunately, that is not one of the options available when using Word's mail-merge feature. The only answer to accomplishing this task is to create a macro that will, based on the merged document (the 300-page one mentioned above) take each section and save it to its own document file.

If you look in Microsoft's Knowledge Base, you will find that there is an old article that deals with this very issue:

The macro presented in the article, even though it was written for an older version of Word, will work just fine in later versions. It allows you to separate a merged document into individual files, based on the section breaks:

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

It is important to realized, however, that this macro will only work if the only place that section breaks occur is between merged documents. If your original document includes section breaks, then the macro will not provide satisfactory results.
