Hallo,

Ich danke vielmals. Habe es jetzt nochmal getestet und den gesammten Code ein bissl schön gemacht und es Funzt alles so wie ich es gerne hätte.

Hier der Code:

Option Explicit

Sub ImportCSV()
    
    Dim shtImport   As Worksheet
    Dim strFileName As String
    Const Num1     As Long = 1
    Dim RowsMax1    As Long
    Dim RowsMax2   As Long
    Dim Row         As Long

    ' Delete Clear Rows
With Import
    RowsMax2 = .UsedRange.Rows.Count
    
    For Row = RowsMax2 To 4 Step -1
    
    If Application.WorksheetFunction.CountA(.Rows(Row)) = 0 Then
     .Rows(Row).Delete
    End If
    Next Row
End With

    ' Detect RowMax for Import
RowsMax1 = Import.UsedRange.Rows.Count
RowsMax1 = CDbl(Num1) + CDbl(RowsMax1)
         
    ' Change the name "Import" according to your sheet name.
Set shtImport = Sheets("Import")
      
    ' Show the file dialog and select a CSV file.
With Application.FileDialog(msoFileDialogFilePicker)
    .AllowMultiSelect = False
    .Title = "Select a CSV file!"
    .Filters.Clear
    .Filters.Add "Semicolon Separated Values", "*.csv"
    .Show
        
    If .SelectedItems.Count = 0 Then
        MsgBox "You did't select a CSV file!", vbExclamation, "Canceled"
        Exit Sub
    Else
        strFileName = .SelectedItems(1)
    End If
End With
    
With ActiveSheet.QueryTables.Add(Connection:="TEXT;" & strFileName, Destination:=Range("$A" & RowsMax1))
    .Name = "strFileName"
    .FieldNames = True
    .RowNumbers = False
    .FillAdjacentFormulas = False
    .PreserveFormatting = True
    .RefreshOnFileOpen = False
    .RefreshStyle = xlInsertDeleteCells
    .SavePassword = False
    .SaveData = True
    .AdjustColumnWidth = False '''
    .RefreshPeriod = 0
    .TextFilePromptOnRefresh = False
    .TextFilePlatform = 65001
    .TextFileStartRow = 1
    .TextFileParseType = xlDelimited
    .TextFileTextQualifier = xlTextQualifierDoubleQuote
    .TextFileConsecutiveDelimiter = False
    .TextFileTabDelimiter = False
    .TextFileSemicolonDelimiter = True
    .TextFileCommaDelimiter = False
    .TextFileSpaceDelimiter = False
    .TextFileColumnDataTypes = Array(4, 2, 2, 2, 1)
    .TextFileTrailingMinusNumbers = True
    .Refresh BackgroundQuery:=False
End With
    
    ' Turn OFF the Screenupdating
Application.ScreenUpdating = False
    
    ' Check if the selected file is CSV file.
If UCase(Right(strFileName, 3)) <> "CSV" Then
    MsgBox "The file you select is not a CSV file!", vbCritical, "Error!"
    Exit Sub
End If
    
    ' Remove duplicated Rows
Range("A3:E320000").Select
ActiveSheet.Range("$A$3:$E$320000").RemoveDuplicates Columns:=Array(1, 2, 3, 4, 5), _
Header:=xlYes
    
    ' Leere Zelen loeschen
With Import
    RowsMax2 = .UsedRange.Rows.Count
    For Row = RowsMax2 To 4 Step -1
    If Application.WorksheetFunction.CountA(.Rows(Row)) = 0 Then
        .Rows(Row).Delete
    End If
Next Row
End With

    ' Turn ON the Screenupdating
    Application.ScreenUpdating = True
    
    
    ' Inform the user about the process.
    MsgBox "The file " & strFileName & " was successfully imported on sheet " & _
    shtImport.Name & "!", vbInformation, "Done"
     
End Sub
