Boas;

Fiz este simples Sub que permite exporta qualquer dados de um determinado ListView para Excel muito facilmente.. penso que poderá ser ultil para quem precisar.

    Private Sub ExportarXLS(ByVal oListView As ListView)
        Try
            Using oSF As New SaveFileDialog
                oSF.Filter = "Ficheiro do Excel (*.xls)|*.xls"
                If oSF.ShowDialog = Windows.Forms.DialogResult.OK Then
                    ' Cria o ficheiro..
                    Using oSR As New StreamWriter(oSF.FileName, False, Encoding.Default)
                        Const cQuo As String = """"
                        Const cTab As String = vbTab
                        ' Adiciona o cabeçalho..
                        For Each oColumn As ColumnHeader In oListView.Columns
                            If Not oColumn.Index = (oListView.Columns.Count - 1) Then
                                oSR.Write(oColumn.Text & cTab)
                            Else
                                oSR.Write(oColumn.Text)
                            End If
                        Next
                        oSR.WriteLine()
                        ' Escreve todos os rows..
                        For Each oItem As ListViewItem In oListView.Items
                            ' Escreve o primeiro item
                            oSR.Write(cQuo & oItem.Text & cQuo & cTab)
                            ' Escreve os restantes subitems
                            For i As Integer = 1 To (oItem.SubItems.Count - 1)
                                oSR.Write(cQuo & oItem.SubItems(i).Text & cQuo & cTab)
                            Next
                            oSR.WriteLine()
                        Next
                        MessageBox.Show("Ficheiro exportado com êxito!", My.Application.Info.Title, MessageBoxButtons.OK, MessageBoxIcon.Asterisk)
                    End Using
                End If
            End Using
        Catch ex As Exception
            MessageBox.Show(ex.Message, My.Application.Info.Title, MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try
    End Sub
