Is there anyone who can help me convert a VBA code to Google Apps Script.

This code works perfectly in Excel, but now people also want it in Google Workspace

See the VBA code below.

Sub Bestand_invoegen()

 Sheets("Orginele lijst").Activate
  Cells.ClearContents
 
 Sheets("Bestand invoegen").Activate
 
    Dim FileToOpen As Variant
    Dim OpenBook As Workbook
    Application.ScreenUpdating = False
    FileToOpen = Application.GetOpenFilename(Title:="Browse voor je bestand & Import Range", FileFilter:="Excel Files (*.xls*),*xls*")
    If FileToOpen <> False Then
        Set OpenBook = Application.Workbooks.Open(FileToOpen)
        OpenBook.Sheets(1).Range("A1:N50").Copy
        ThisWorkbook.Worksheets("Orginele lijst").Range("A1").PasteSpecial xlPasteValues
        OpenBook.Close False
        
    End If
    Application.ScreenUpdating = True
    
 Sheets("Orginele lijst").Activate
 
  Range("E2:N50") = Range("E2:N50").Value
 
 Sheets("Bestand invoegen").Activate

End Sub

Thanks

I tried Google’s “Macro Converter” add-on. But that didn’t work because I don’t have an Enterprice license.
The code erases the data from a particular sheet and then opens a selection screen to select a file from which a specific range is selected and copied to the erased sheet.
I’ve scoured the internet for solutions but each time it opens Google Drive and not the local drive. Because that is where the files from which the data must come are located. In Excel this is all possible with no problem.
Can anyone help me get this done in Google Apps Script.

Thanks
