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.

LOCAL loCsv
LOCAL lnSuccess
LOCAL lcCsvDoc

*  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

loCsv = CreateObject('Chilkat.Csv')

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

*  Load the CSV records from the file:

lnSuccess = loCsv.LoadFile("sample.csv")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loCsv.LastErrorText)
    QUIT
ENDIF

*  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
loCsv.SetCell(0,3,"cheese,baguette")

*  A field may also contain double-quotes:
*  Change blue to shiny "metallic" blue
loCsv.SetCell(1,1,[shiny "metallic" blue])

*  Write the updated CSV to a string and display:

lcCsvDoc = loCsv.SaveToString()
? lcCsvDoc

*  Save the CSV to a file:
lnSuccess = loCsv.SaveFile("out.csv")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loCsv.LastErrorText)
ENDIF

*  The out.csv contains this:
*  year,color,country,food
*  2001,red,France,"cheese,baguette"
*  2005,"shiny ""metallic"" blue","United States",hamburger
*  2008,green,Italy,pasta
*  1998,orange,Japan,sushi
