Excel makes me *. csv file with CR / LF characters at the end of each line, but does not know StringUtils library symbol CR.

Is there a possibility that with the command "StringUtils1.LoadCSV (dir, Filename,",")" to open the *. csv file with excel made​​?

Does anyone know what the VB macro to remove the CR character at the end of each row in excel *. csv file?

thanks for your help

"correctly"? Ok, but how I use it?
if I save *. csv file with the command "StringUtils1.SaveCSV2 (Dir, Filename," ", Sheet1, headers)" is not written to the CR character. And so the file can be opened by "StringUtils1.LoadCSV2 (Dir, Filename," ", headers)" without error. If you open the file with CR / LF ending, we make a mistake B4a "LastException java.lang.StringIndexOutOfBoundsException". I use the following code.

Where do I make a mistake?

Sub LoadTableFromCSV

Dim fd As FileDialog
Dim filename As String
Dim dir As String
Dim ret As String
Dim list1 As List
Dim Vrsta() As String
Dim x As Int

fd.FilePath="/mnt/sdcard/my document/El izdajnice"
fd.ShowOnlyFolders = False
fd.FastScroll = True


ret = fd.Show("Izberi datoteko", "Yes", "No", "Maybe", Bmp)   


   For i = table.NumberOfViews -1 To 0 Step -1
      table.RemoveViewAt(i)
   Next
 table.Height = 0dip
'x=table.NumberOfViews
'Log("table numberofviews after: " & x)

list1=StringUtils1.LoadCSV(dir,Filename,";")

x=list1.Size
Log ("size list1: " & x)
      ColumnWidth(0) = 10%x      
      ColumnWidth(1) = 55%x
      ColumnWidth(2) = 20%x
      ColumnWidth(3) = 15%x
      TotalColumnWidth(0) = 0dip
For ii=0 To list1.Size-1
   Vrsta = List1.Get(ii)
   For i = 0 To 4
      Dim l As Label
      l.Initialize("cell")
      l.Text = vrsta(i)
      l.Gravity = Alignment
      l.TextSize = FontSize
      l.TextColor = FontColor
      Dim rc As RowCol
      rc.Initialize
      rc.Col = i
      rc.Row = NumberOfRows
      l.Tag = rc
      
      table.AddView(l, TotalColumnWidth(i), RowHeight * NumberOfRows, ColumnWidth(i), RowHeight)
   Next
      Table.Height = NumberOfRows * RowHeight
Next
   Page3.naziv=GetCell(2,3)
End Sub

No problem.
When I try to load "NNO Hotedaršica.csv"( create by excel) Android application makes a mistake.

When the upload file "lukovica.csv" (create by andoroid app) everything is all right.

Hi!

The above example does not work for me. I enclose an application to your case (with DirAsset *. csv file). I think it's really an error in the format *. csv file. Do you have any idea how to fix it?

Thank you for your efforts
