Dear Sir,
I have a CSV (delimited character is  ;) file and want to convert into EXCEL file  using a VB program directly . For this I written following code :

Dim ex1 As Excel.Application
Dim ex2 As Excel.Workbook
Set ex1 = CreateObject("excel.application")
Set ex2 = ex1.Workbooks.Open("c:\a.csv")

ex1.Visible = False
ex2.SaveAs ("c:\bvm1.xls")
ex1.Quit
End Sub


My problem is that , I got the file in EXCEL , but delimeter characters are appearing in EXCEL file and no column wise seperation as per Delimeter character is made .
Kindly guide me with a sample code how to achieve the same .

Try this:

Set ex2 = ex1.Workbooks.Open("c:\a.csv", 1, False, 2)

Try this:

    Dim ex1 As Excel.Application
    Dim ex2 As Excel.Workbook
    ex1 = CreateObject("excel.application")
    ex2 = ex1.Workbooks.Open("C:\a.csv", , , , , , , , Chr(44))
    ex1.Visible = False
    ex2.SaveAs("c:\bvm1.xls")
    ex1.Quit()


It asks you to save over bvm1.xls, if you say choose to overwrite it will make the .xls file open in the respected columns, without commas.

Have you tried using a comma instead of a ; for the delimeter?

As suggested by Cwile, I tried but it is not working . The generated XLS file still has Delimeter Character and Excel is not able to open the file as a true xls file , rather it identifies it as a csv file only .

Did you try my solution? It explicitly addresses CSV import.

Hi,

Here's some VB Code that I'd suggest:

    Dim x
    Dim MyString As String
    Dim Newstring As String
    Dim Oneletter
    ConvertedName = "C:\result.xls"
    sSourceFile = "C:\test.csv"
    Open ConvertedName For Output As #2
    Open sSourceFile For Input As #1
    Do While Not EOF(1)
        Input #1, MyString
        For x = 1 To Len(MyString)
            Oneletter = Mid(MyString, x, 1)
            If Asc(Oneletter) = 59 Then
                Oneletter = vbTab
            End If
            DoEvents
            Newstring = Newstring & Oneletter
        Next x
        Print #2, Newstring
        Newstring = ""
        DoEvents
    Loop
    Close #1
    Close #2


I've tested it at my systems and it worked ... if does not work at your systems please let me know!

Best regards,
Raisor

You can. of course explicitly name the parameters too:

ex1.Workbooks.Open FileName:="c:\a.csv", Format:=xlCSV, Delimiter:=","

Hi,

I might add that I've placed:

test1;test2;test3
test4;test5;test6

in a file named "C:\test.csv"

... and it turned out to be well formated "C:\result.xls"

;-))

As suggested by Cwile , I tried and incase Delimeter Character used is "," then I get proper XLS output file generated . But incase Delimeter is ";" then output XLS file has  all delimeter character in it and not properly formated .

Kindly help me .

Hi,

Have you tried yet?:

    Dim x
    Dim MyString As String
    Dim Newstring As String
    Dim Oneletter
    ConvertedName = "C:\result.xls"
    sSourceFile = "C:\test.csv"
    Open ConvertedName For Output As #2
    Open sSourceFile For Input As #1
    Do While Not EOF(1)
        Input #1, MyString
        For x = 1 To Len(MyString)
            Oneletter = Mid(MyString, x, 1)
            If Asc(Oneletter) = 59 Then
                Oneletter = vbTab
            End If
            DoEvents
            Newstring = Newstring & Oneletter
        Next x
        Print #2, Newstring
        Newstring = ""
        DoEvents
    Loop
    Close #1
    Close #2

... placing:

test1;test2;test3
test4;test5;test6

in a file named: "C:\test.csv"

... and if you tried, what went wrong?

As I've stated ... I've tested the code on my systems and it perfectly worked the way you'd asked for ...

I misread your original post.
Here is something quick I sorta thought up that you may wish to try:
Need the IMPORTS SYSTEM.IO at the beginning. Could convert the targets and what not to variables if you'd like. When it asks to save the file, just make sure that the file type is set to .xls and not .csv and it should convert the semi-colons to commas and then save fine for excel format.

Dim ex1 As Excel.Application
    Dim ex2 As Excel.Workbook
    Dim slines As String
    Dim target As String = "c:\a.csv"
    Dim x As Integer = 0

    TextBox1.Visible = False '// hide the textbox

    For Each slines In File.ReadAllLines(target)
      If x > 0 Then '// if you don't want the column headers
        TextBox1.Text = TextBox1.Text & Replace(slines, Chr(59), Chr(44)) & vbCrLf
      End If
      x = x + 1
    Next
    'TextBox1.Visible = True

    '// creat temp file to store new data
    File.WriteAllText("c:\temp.csv", TextBox1.Text)


    ex1 = CreateObject("excel.application")
    ex2 = ex1.Workbooks.Open("C:\temp.csv", , , , , , , , Chr(44))
    ex1.Visible = False
    ex2.SaveAs("c:\bvm1.xls")
    ex1.Quit()

    '// delete temp file
    File.Delete("c:\temp.csv")

forgot to add that you need to make sure that the textbox's multiline is set to true.

By the way, you'll want to save and close correctly - try:
        ex2.SaveAs("c:\temp\zzz.xls", Excel.XlFileFormat.xlWorkbookNormal)
        ex2.Close(False)

Hi,

I haven't tested other approaches but mine ... mine worked out on my systems and the solution did what bvmittal was asking for (if I understood his question well) ... if it didn't work out for bvmittal ... well, then I'm sorry ;-))
