VBA Code-csv file into excel- from general to text

I have a “.csv” file. Now we would like to copy data from this file into another Excel file. Doing this with my simple macro, I encounter a problem in some columns as I have numbers which are stored there in the format: “0000” and “01234567890”. Pasting the data makes then a “0” or “E09” out of the former source.

If I did that manually, I would do the following:

1.Copy from .csv file
2.Paste > “use text import wizard” > changing the respective fields (LFNR_... and EXTERNAL_ID) from “general” to “text”.
3.Would be happy – everything looks fine

This is current macro:

ImportFileboxData Macro
'
Dim dateiname As String
dateiname = ThisWorkbook.Worksheets("MAS").Range("E7").Value
'
ThisWorkbook.FollowHyperlink ThisWorkbook.Worksheets("MAS").Range("E8").Value

Range("A2:AL10000").Select
Application.CutCopyMode = False
Selection.Copy
Windows("CreateReports.xlsm").Activate
Sheets("RawData").Select
Range("A2").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False

Windows(dateiname).Activate
ActiveWorkbook.Close (True)

Windows("CreateReports.xlsm").Activate
Sheets("MAS").Select

Do you know a trick how to paste csv-data into an excel spreadsheet keeping the data okay?
