Hi Experts,

I have piece of code which import all .csv data in to one .csv file (import.csv) and create import.txt file from import.csv file. All is working well just need to add one more procedure while creating import.txt. Need to sort data in A to Z except header.
here is the code
Sub csvTotxt()
    Dim strData As String
    Dim oRE As Object
    Dim oMatches As Object
    Dim oM As Object
    Dim oSM As Object
    Dim oWsh As Object
    Const ForReading = 1, ForWriting = 2, ForAppending = 3
    Dim oFS As Object, oTS As Object
    Dim lngSM As Long
    Dim vOutput As Variant
    Const cPath As String = "C:\Test\"
    Const cHeader As String = "<ticker>,<per>,<date>,<open>,<high>,<low>,<close>,<vol>,<o/i>"
    
    Set oWsh = CreateObject("wscript.shell")
    Set oFS = CreateObject("Scripting.FileSystemObject")

    Set oRE = CreateObject("vbscript.regexp")
    oRE.Global = True
    oRE.Pattern = "(\w[^,]*),[^,]*,(\d[^,]*),([^,]*),([^,]*),([^,]*),[^,]*,[^,]*,([^,]*),[^,]*,([^,]*).*?,\n"
    
    'combine csv files
    oWsh.Run "cmd /c copy " & cPath & "*.csv " & cPath & "import.csv", 0, True
    
    Set oTS = oFS.OpenTextFile(cPath & "import.csv", ForReading, False, False)
    strData = oTS.readall
    oTS.Close
    Set oTS = oFS.OpenTextFile(cPath & "import.txt", ForWriting, True, False)
    oTS.writeline cHeader
    
    If oRE.test(strData) Then
        ReDim vdata(1 To 9)
        Set oMatches = oRE.Execute(strData)
        For Each oM In oMatches
            With oM
                vdata(1) = .submatches(0)
                vdata(2) = "D"
                vdata(3) = Format(.submatches(6), "yyyymmdd")
                vdata(4) = .submatches(1)
                vdata(5) = .submatches(2)
                vdata(6) = .submatches(3)
                vdata(7) = .submatches(4)
                vdata(8) = .submatches(5)
                vdata(9) = 0
                oTS.writeline Join(vdata, ",")
            End With
        Next
        oTS.Close
    End If
    
End Sub

I don't do any thing with CSV file ...I use only .txt file.

so expecting final result like this Final output  I not sure about how it will be done but logically I think this way, I may be completely wrong on this Assumption
i need only .txt file in sorted A to Z.

Thanks

If you can open the txt file in Excel, that is the most logical place to sort the data.

Do you have Notepad++?  Use it to sort the file
(already stated) Use Excel to sort the file
Can you run Powershell?  If so, use it to sort the file

Here is a quick and dirty attempt at doing the sort.
Sub csvTotxt()
    Dim strData As String
    Dim oRE As Object
    Dim oMatches As Object
    Dim oM As Object
    Dim oSM As Object
    Dim oWsh As Object
    Const ForReading = 1, ForWriting = 2, ForAppending = 3
    Dim oFS As Object, oTS As Object
    Dim lngSM As Long
    Dim vOutput As Variant
    Const cPath As String = "C:\Test\"
    
    '                          <ticker>
    Const cHeader As String = "!!!!!!!!,<per>,<date>,<open>,<high>,<low>,<close>,<vol>,<o/i>"
    
    Set oWsh = CreateObject("wscript.shell")
    Set oFS = CreateObject("Scripting.FileSystemObject")

    Set oRE = CreateObject("vbscript.regexp")
    oRE.Global = True
    oRE.Pattern = "(\w[^,]*),[^,]*,(\d[^,]*),([^,]*),([^,]*),([^,]*),[^,]*,[^,]*,([^,]*),[^,]*,([^,]*).*?,\n"
    
    'combine csv files
    oWsh.Run "cmd /c copy " & cPath & "*.csv " & cPath & "import.csv", 0, True
    
    Set oTS = oFS.OpenTextFile(cPath & "import.csv", ForReading, False, False)
    strData = oTS.readall
    oTS.Close
    
    Set oTS = oFS.OpenTextFile(cPath & "import.txt", ForWriting, True, False)

            End With
        Next
        oTS.Close
    End If
    
    oWsh.Run "cmd /c sort " & cPath & "import.txt /o " & cPath & "sortedimport.txt", 0, True

@David

The problem isn't as simple as that.  Visit the prior related question and look at the posted code for a better understanding.

powershell script change as required
$infile = "F:\Downloads\cm01OCT2014bhav.csv"
$outfile = "C:\temp\outfile.txt"
$csv = import-csv -Path $infile  
$csv | sort-object  {$_.Symbol}|convertto-csv -NoTypeInformation | Out-File $outfile

as required
All the csv files in a directory have to be processed as described in the prior related question, not just a single file.  Moreover, only certain columns should be included in the output (one added and one formatted), and a new header supplied.

Did you follow the same pattern of the string constant file path in the accepted solution comment?

What does your code look like, specifically the const line?
