$oCsv = ObjCreate("Chilkat.Csv")

;  Prior to loading the CSV file, indicate that the 1st row
;  should be treated as column names:
$oCsv.HasColumnNames = True

;  Load the CSV records from the file:

$bSuccess = $oCsv.LoadFile("sample.csv")
If ($bSuccess <> True) Then
    ConsoleWrite($oCsv.LastErrorText & @CRLF)
    Exit
EndIf

;  Change "cheese" to "baguette"
;  ("cheese" is at row=0, column=3
$bSuccess = $oCsv.SetCell(0,3,"baguette")

;  Change "blue" to "magenta"
$bSuccess = $oCsv.SetCell(1,1,"magenta")

;  Write the updated CSV to a string and display:
Local $sCsvDoc
$sCsvDoc = $oCsv.SaveToString()
ConsoleWrite($sCsvDoc & @CRLF)

;  Save the CSV to a file:
$bSuccess = $oCsv.SaveFile("out.csv")
If ($bSuccess <> True) Then
    ConsoleWrite($oCsv.LastErrorText & @CRLF)
