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.

    CkString strOut;

    //  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

    CkCsv csv;

    //  Prior to loading the CSV file, indicate that the 1st row
    //  should be treated as column names:
    csv.put_HasColumnNames(true);

    //  Load the CSV records from the file:
    bool success;
    success = csv.LoadFile("sample.csv");
    if (success != true) {
        strOut.append(csv.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    //  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
    csv.SetCell(0,3,"cheese,baguette");

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

    //  Write the updated CSV to a string and display:
    const char * csvDoc;
    csvDoc = csv.saveToString();
    strOut.append(csvDoc);
    strOut.append("\r\n");

    //  Save the CSV to a file:
