Append line to an existing csv file

(0) ShareShare

Posted on by Community Member

Hi All,

I want to open an existing csv file and append record/line to it from AX 2012 Job. Every time I am trying to do that it is replacing the file with new set of record.

Please advice.

Thanks and Regards,

Arindam

    Let's start with an example:

    #File
CommaTextIo io = new CommaTextIo(@'c:\temp\test.csv', #io_append);
;
io.write("abcd", 123);

    You can run this code several times and it always add another line to the file.

    The second parameter of CommaTextIo's constructor is crucial - if you use #io_write (or 'w') instead, the existing file content will be overwritten.

    Hi Martin,

    It worked. thank you. I was using #io_write. In that way every time it was creating a new file and line. Now after using #io_append I am getting desired out put.

    Thank you.

    If you have more files, you'll use the same, just several times (once for each file).

    The other question isn't related to the topic of this thread ("Append line to an existing csv file"); please create a new one (with an appropriate title and tags) and explain your problem there.
