i'm creating a .csv file on the fly, thus am enclosing all the data within double quotes.
how to put in a newline character is the problem. for eg:-
i tried the following -

"header1","header2","header3"\n"data1","data2","da ta3"\n"data11","data22","data33"

and

"header1","header2","header3 \n"\r\n "data1","data2","data3 \n"\r\n "data11","data22","data33"

so that the output looks like

header1 header2 header3
data1 data2 data3
data11 data22 data33

thanks a lot for your help

Is there any code you have written for this? Please post.

I'm not sure what the end use of the .csv file would be. What's the purpose of creating this file?

You might want to try ASCII newline character. Don't really have much experience with creating .csv files.
