Hi,
You can use the below code: You didnt mention ranges or anything! So i made it generic and u can tweak it as much as you want!
Sub openz()
Dim sht As Worksheet: Set sht = Sheets("Desintation sheet name")
Dim wb As ThisWorkbook
Application.DisplayAlerts = False
Workbooks.Open Filename:="write the full path of the file including the file name and extension ie .XLSX"
Sheets("Source").Range("A1:A" & Sheets("Source").Cells(Cells.Rows.Count, "A").End(xlUp).Row).Copy
wb.Activate
sht.Range("A1").PasteSpecial xlPasteValues
Workbooks("Filename").Close savechanges = False
Application.DisplayAlerts = True
End Sub
