(PowerBuilder) CSV Special Chars - Comma, Double-Quotes

The Chilkat CSV class/component automatically handles special characters which include double-quotes, and the delimiter character (comma or semicolon).

The Chilkat CSV library/component/class is freeware. The downloads for .NET, C++, Perl, Java, Ruby, and Python contain all of the Chilkat classes, some of which are freeware and some of which require licensing.

//  This example program loads a file (sample.csv)
//  that contains this content:
// 
//  year,color,country,food
//  2001,red,France,cheese
//  2005,blue,"United States",hamburger
//  2008,green,Italy,pasta
//  1998,orange,Japan,sushi
// 
//  The first row contains the column names.
//  This file is available at:
//  http://www.chilkatsoft.com/testData/sample.csv

    destroy loo_Csv

end if

//  Prior to loading the CSV file, indicate that the 1st row
//  should be treated as column names:
loo_Csv.HasColumnNames = 1

//  Load the CSV records from the file:

li_Success = loo_Csv.LoadFile("sample.csv")
if li_Success <> 1 then
    Write-Debug loo_Csv.LastErrorText
    destroy loo_Csv
    return
end if

//  A field may contain the delimiter character (in this case
//  the delimiter is a comma):
//  Change "cheese" to "cheese,baguette"
//  ("cheese" is at row=0, column=3

//  A field may also contain double-quotes:
//  Change blue to shiny "metallic" blue
li_Success = loo_Csv.SetCell(1,1,"shiny \"metallic\" blue")

//  Write the updated CSV to a string and display:

ls_CsvDoc = loo_Csv.SaveToString()
Write-Debug ls_CsvDoc

//  Save the CSV to a file:
li_Success = loo_Csv.SaveFile("out.csv")
if li_Success <> 1 then
    Write-Debug loo_Csv.LastErrorText

//  The out.csv contains this:

//  2005,"shiny ""metallic"" blue","United States",hamburger
//  2008,green,Italy,pasta
