CSV Special Chars - Comma, Double-Quotes

See more CSV Examples

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 lnSuccess

lnSuccess = 0

* 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
    ? loCsv.LastErrorText
    RELEASE loCsv
    CANCEL
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
lnSuccess = loCsv.SetCell(0,3,"cheese,baguette")

* A field may also contain double-quotes:
* Change blue to shiny "metallic" blue
lnSuccess = 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
    ? 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,sush
