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.

// 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:

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

// Load the CSV records from the file:

llSuccess = loCsv.LoadFile("sample.csv")
if (llSuccess <> .T.) then
    ? loCsv.LastErrorText
    release loCsv
    return
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
llSuccess = loCsv.SetCell(0,3,"cheese,baguette")

// A field may also contain double-quotes:
// Change blue to shiny "metallic" blue
llSuccess = 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:
llSuccess = loCsv.SaveFile("out.csv")
if (llSuccess <> .T.) 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
