Good solution Alex, we shouldn't have to do this, but we do, EXCEL just won't end. I took your solution and created the code below, I call ExcelProcessInit before my app imports or exports with Excel, then call ExcelProcessKill after it's complete.

Private mExcelProcesses() As Process

Private Sub ExcelProcessInit()
  Try
    'Get all currently running process Ids for Excel applications
    mExcelProcesses = Process.GetProcessesByName("Excel")
  Catch ex As Exception
  End Try
End Sub

Private Sub ExcelProcessKill()
  Dim oProcesses() As Process
  Dim bFound As Boolean

  Try
    'Get all currently running process Ids for Excel applications
    oProcesses = Process.GetProcessesByName("Excel")

    If oProcesses.Length > 0 Then
      For i As Integer = 0 To oProcesses.Length - 1
        bFound = False

        For j As Integer = 0 To mExcelProcesses.Length - 1
          If oProcesses(i).Id = mExcelProcesses(j).Id Then
            bFound = True
            Exit For
          End If
        Next

        If Not bFound Then
          oProcesses(i).Kill()
        End If
      Next
    End If
  Catch ex As Exception
  End Try
End Sub

Private Sub MyFunction()
  ExcelProcessInit()
  ExportExcelData() 'Whatever code you write for this...
  ExcelProcesKill()
End Sub
