True if no changes have been made to the specified workbook since it was last saved. Read/write Boolean.
Remarks
If a workbook has never been saved, its Path property returns an empty string ("").
You can set this property to True if you want to close a modified workbook without either saving it or being prompted to save it.
Example
This example displays a message if the active workbook contains unsaved changes.
If Not ActiveWorkbook.Saved Then
MsgBox "This workbook contains unsaved changes."
End If
This example closes the workbook that contains the example code and discards any changes to the workbook by setting the Saved property to True.
ThisWorkbook.Saved = True
ThisWorkbook.Close
