Problem in writiing data to UTL_File

Question

Hello Friends,
I'm using UTL_FILE to write the data into csv file, but in the table 1 description column is there which contains 3000 characters.
My problem is i'm not able to write more than 750 characters in csv file and if i tried to do so then get the FILE_WRITE_ERROR. error msg
I tried by breaking the column into 3 different strings by giving the column as diffrent-different aliases but facing the same problem.
Please help me to write all the characters i.e 3000 charcters in a file.
Is there any character length limitation in csv file?
Regards,
Anand
