open file path

Hi.

i'm using Application.GetOpenFilename to open a file. But i want it to
open the file in the active workbook insted of a new one. and in the sheet that i want.

Dim FileName As Variant
    Dim Filt As String, Title As String
    Dim FilterIndex As Integer, Response As Integer
    
          ChDrive "H:\"
           ChDir "H:\tonn"
        Filt = "all Files (*.), *."
          FilterIndex = 5
           Title = "Please select a different File"
           FileName = Application.GetOpenFilename(FileFilter:=Filt, _
            FilterIndex:=FilterIndex, Title:=Title)
          If FileName = False Then
            Response = MsgBox("No File was selected", vbOKOnly & vbCritical, "Selection Error")
            Exit Sub
        End If
          Response = MsgBox("You selected " & FileName, vbInformation, "Proceed")
            Workbooks.Open FileName

Thank u for u'r reply. but i think i did'nt make myself clear enough

it's not a workbook. its a txt file that is saved on the computer. i know how to import a spesific file. but i just want to open the file path and then select the file i want to import with my mouse. but when i do this with the code that i posted. the file is inserted in a new workbook instead og the workbook i'm working in.
