Insert rows according to certain positions

[Andrea Mejia]

Hello everybody!
I am new doing macros in VBA and would like someone to help me please.
I have a plain txt file with the numeric positions where I should insert empty rows in an excel. How should the macro be for this scenario, considering that I don't know how to import a txt?

For example, my txt file has positions like: "20, 35, 46".
The above numbers correspond to the positions where you should insert empty rows in Excel.

I would be infinitely grateful if you could help me. thank you very much!!!!!

Sub Del_by_txt()
Dim t As String, k, ar
    Open "D:\YOUR_TEXT_FILE.txt" For Input As #1
    While Not EOF(1)
        Line Input #1, t
        k = (Len(t) - Len(Replace(t, Chr(44), ""))) / Len(Chr(44))
        ReDim ar(1 To k + 1, 1 To 1)
        ar = Split(t, Chr(44))
            For k = UBound(ar) To 0 Step -1
                ActiveSheet.Rows(Trim(ar(k))).Delete
            Next k
    Wend
    Close #1
End Sub
