Answer 1

There is no Excel JavaScript API that will return the dirty cells, but it's a good idea. Please suggest it at Office Developer Voice.

Answer 2

Since Excel doesn't natively have a dirty flag, you'll need to produce one via one of two methods:

Catch the cell edit event and record a list of edited cells that are dirty.

Dim Dirty As New Collection

Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
    Dim sheet As Worksheet
    Set sheet = Sh
    Dirty.Add (sheet.Name + "!" + Target.Address)
End Sub

OR

When you need the dirty flag, open the saved copy behind the scenes and compare the two to see what has changed.
