Excel modify macro for "data from text" to open dialog box?

Question

So I work with CSV files and I need to open excel go to Data -> From text and format certain columns certain ways. I recorded a macro that does that but it always opens the file I used when recording the macro. How do I modify the macro so it opens the dialog box and let me choose a file each time? I found this piece of code on the internet but I don't know how to integrate it with my recorded macro in VBA.

Dim MyFile As String
MyFile = Application.GetOpenFilename()

Now how and where and what do I replace in the below macro (the code for which is created using the "record macro" button in excel)?

Sub random_name()
'
' random_name Macro
'

'
    With ActiveSheet.QueryTables.Add(Connection:= _
        "TEXT;MyFile = Application.GetOpenFilename()" _
        , Destination:=Range("$A$1"))
        .Name = "filename"
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .TextFilePromptOnRefresh = False
        .TextFilePlatform = 1252
        .TextFileStartRow = 1
        .TextFileParseType = xlDelimited
        .TextFileTextQualifier = xlTextQualifierDoubleQuote
        .TextFileConsecutiveDelimiter = False
        .TextFileTabDelimiter = True
        .TextFileSemicolonDelimiter = False
        .TextFileCommaDelimiter = False
        .TextFileSpaceDelimiter = False
        .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1, 2, 2, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, _
        1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)
        .TextFileTrailingMinusNumbers = True
        .Refresh BackgroundQuery:=False
    End With
End Sub

Thanks!

Hey I have modified your code:

Sub random_name()
'
' random_name Macro
'

'
Dim connectioString As String

connectioString = "TEXT;" & ListFile


    With ActiveSheet.QueryTables.Add(Connection:= _
        connectioString _
        , Destination:=Range("$A$1"))
        .Name = "filename"
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .TextFilePromptOnRefresh = False
        .TextFilePlatform = 1252
        .TextFileStartRow = 1
        .TextFileParseType = xlDelimited
        .TextFileTextQualifier = xlTextQualifierDoubleQuote
        .TextFileConsecutiveDelimiter = False
        .TextFileTabDelimiter = True
        .TextFileSemicolonDelimiter = False
        .TextFileCommaDelimiter = False
        .TextFileSpaceDelimiter = False
        .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1, 2, 2, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, _
        1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)
        .TextFileTrailingMinusNumbers = True
        .Refresh BackgroundQuery:=False
    End With
End Sub

beneth this paste this function:

Function ListFile()
' ----- Creating a dialog object -----------------------------------
    Dim oDiag As FileDialog
    Dim vrtSelectedItem As Variant
    Dim i As Integer
    Set oDiag = Application.FileDialog(msoFileDialogFilePicker)
    i = 0
    With oDiag
' ----- Going thru all of the files --------------------------------
        .AllowMultiSelect = False
        If .Show = -1 Then

           ListFile = .SelectedItems(1)

        End If
    End With

    Set oDiag = Nothing

End Function

I am not at this point a 100% sure if filedialog required a reference tell me if it works :)

Try this:

Path = Application.GetOpenFilename()
    With ActiveSheet.QueryTables.Add(Connection:= _
        "TEXT;" & Path, Destination:=Range("$A$1"))
