I need to import excel file data into limdep. But I cannot convert text of excel into ASCII format as I cannot find The Text converter program in excel.
Is there any other way to convert text into the ASCII format?
This procedure allows you to export data from a worksheet range to a text file. You may specify the character (e.g, a space, tab, pipe, comma, etc) that separates the exported elements. Each row of cells in the worksheet is written to one line within the text file, and each item in that line is separated by the specified delimiter character. Any single character may be used as the delimiter.
The ExportToTextFile procedure follows. The parameters to ExportToTextFile are described in the following table:
Parameter
Description
FName
The name of the file to which the data will be written. The file will be created if it does not exist. See AppendData below.
Sep
The character that is to separate the elements on each row of the exported file. Typically, this is vbTab, a space, a comma, semicolor, or pipe ( | ). Any character may be used.
SelectionOnly
If True, only the currently selected cells are exported. If False, the entire used range of the worksheet is exported.
AppendData
If True and FName exists, data is written to the end of the text file, preserving the existing contents. If False, the existing contents of FName are destroyed and only the newly exported data will appear in the output file.

Because the ExportToTextFile procedure accepts input parameters, you must call it from other VBA code, such as the following:
Sub DoTheExport()
ExportToTextFile FName:="C:\Test.txt", Sep:=";", _
SelectionOnly:=False, AppendData:=True
End Sub
In the example DoTheExport procedure above, the file name and the separator character are hard coded in to the code. If you want to prompt the user for the file name and the separator character, use code like the following:
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' DoTheExport
' This prompts the user for the FileName and the separtor
' character and then calls the ExportToTextFile procedure.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Sub DoTheExport()
Dim FileName As Variant
Dim Sep As String
FileName = Application.GetSaveAsFilename(InitialFileName:=vbNullString, FileFilter:="Text Files (*.txt),*.txt")
If FileName = False Then
''''''''''''''''''''''''''
' user cancelled, get out
''''''''''''''''''''''''''
Exit Sub
End If
Sep = Application.InputBox("Enter a separator character.", Type:=2)
If Sep = vbNullString Then
''''''''''''''''''''''''''
' user cancelled, get out
''''''''''''''''''''''''''
Exit Sub
End If
Debug.Print "FileName: " & FileName, "Separator: " & Sep
ExportToTextFile FName:=CStr(FileName), Sep:=CStr(Sep), _
SelectionOnly:=False, AppendData:=True
End Sub
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' END DoTheExport
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
This code will prompt the user for a text file name in which to save the file and for the separator character. If the user cancels either of these dialogs, the procedure is terminated and no export operation is carried out.
Importing A Text File
This procedure allows you to import data from a delimited text file. Each line in the text file is written to one row in the worksheet. Items in the text file are separated into separate columns on the worksheet row based on the character you specify.
If your text file contains greater the 64K records, or you need to split the imported text across multiple worksheets, see Importing Big Text Files Into Excel.
The ImportToTextFIle procedure is shown below. FName is the name of the file to import and Sep is the character that separates column data.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' ImportTextFile
' This imports a text file into Excel.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Public Sub ImportTextFile(FName As String, Sep As String)
Dim RowNdx As Long
Dim ColNdx As Integer
Dim TempVal As Variant
Dim WholeLine As String
Dim Pos As Integer
Dim NextPos As Integer
Dim SaveColNdx As Integer
While Not EOF(1)
Line Input #1, WholeLine
If Right(WholeLine, 1) <> Sep Then
WholeLine = WholeLine & Sep
End If
ColNdx = SaveColNdx
Pos = 1
NextPos = InStr(Pos, WholeLine, Sep)
While NextPos >= 1
TempVal = Mid(WholeLine, Pos, NextPos - Pos)
Cells(RowNdx, ColNdx).Value = TempVal
Pos = NextPos + 1
ColNdx = ColNdx + 1
NextPos = InStr(Pos, WholeLine, Sep)
Wend
RowNdx = RowNdx + 1
Wend
EndMacro:
On Error GoTo 0
Application.ScreenUpdating = True
Close #1
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' END ImportTextFile
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
End Sub
Since ImportTextFile takes input parameters, it should be called from other VBA code:
Sub DoTheImport()
ImportTextFile FName:="C:\Test.txt", Sep:="|"
End Sub
In this code, both the file name and the separator are hard coded into the code. If you want to prompt the user for a file name and separator character, use code like the following:
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' DoTheImport
' This prompts the user for a FileName as separator character
' and then calls ImportTextFile.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Sub DoTheImport()
Dim FileName As Variant
Dim Sep As String
FileName = Application.GetOpenFilename(FileFilter:="Text File (*.txt),*.txt")
If FileName = False Then
''''''''''''''''''''''''''
' user cancelled, get out
''''''''''''''''''''''''''
Exit Sub
End If
Sep = Application.InputBox("Enter a separator character.", Type:=2)
If Sep = vbNullString Then
''''''''''''''''''''''''''
' user cancelled, get out
''''''''''''''''''''''''''
Exit Sub
End If
Debug.Print "FileName: " & FileName, "Separator: " & Sep
ImportTextFile FName:=CStr(FileName), Sep:=CStr(Sep)
End Sub
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' END DoTheImport
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
In this code, the user is prompted for the import file name and the separator character. If either of these prompts are cancelled, the operation is terminated.
