Hi

You can use this code to import the text file. Not sure about the formula. In which range you want the formula ?

Code:
Sub Macro3()
        
    Dim nm  As Name
    
    For Each nm In ThisWorkbook.Names
        If nm.Name Like "dsadas*" Then nm.Delete
    Next
        
    With ActiveSheet.QueryTables.Add(Connection:= _
        "TEXT;C:\Users\bszoverdffy\Desktop\New folder\dsadas.txt", Destination:=Range _
        ("$A$1"))
        .Name = "dsadas_1"
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .TextFilePromptOnRefresh = False
        .TextFilePlatform = 65001
        .TextFileStartRow = 1
        .TextFileParseType = xlDelimited
        .TextFileTextQualifier = xlTextQualifierDoubleQuote
        .TextFileConsecutiveDelimiter = False
        .TextFileTabDelimiter = True
        .TextFileSemicolonDelimiter = False
        .TextFileCommaDelimiter = False
        .TextFileSpaceDelimiter = False
        .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1, 1, 1)
        .TextFileTrailingMinusNumbers = True
        .Refresh BackgroundQuery:=False
    End With
    
    Range("b:b,c:c,f:g").EntireColumn.Delete
    
    Rows("1:1751").Delete Shift:=xlUp
    Rows("771:789").Delete Shift:=xlUp
    
    
End Sub
