It's in post #2...
Do note that it's only designed for importing references in the xml format Word uses - which is what the SourcesExport macro produces.
The following macro converts a document’s Citations & Bibliography to static text. Note the use of WordBasic ! for this. Note also that converting a Bibliography to static text does not remove it’s building block container – a form of content control. A trivially-simple alternative is to save the file in Word's doc format.
Code:
Sub References_Unlink()
Dim Fld As Field, FtNt As Footnote, EndNt As Endnote
With ActiveDocument
For Each Fld In .Fields
If Fld.Type = wdFieldCitation Then
Fld.Select
WordBasic.BibliographyCitationToText
ElseIf Fld.Type = wdFieldBibliography Then
Fld.Select
WordBasic.BibliographyCitationToText
End If
Next
For Each FtNt In .Footnotes
For Each Fld In FtNt.Range.Fields
If Fld.Type = wdFieldCitation Then
Fld.Select
WordBasic.BibliographyCitationToText
End If
Next
Next
For Each EndNt In .Endnotes
For Each Fld In EndNt.Range.Fields
If Fld.Type = wdFieldCitation Then
Fld.Select
WordBasic.BibliographyCitationToText
End If
Next
Next
End With
End Sub
