    Read CSV File

    Sudha K Level 1



           I am using the below function to read csv file. Recently noticed this issue. I did not know why its happening.. is it related to eof reason or any other reason?


           When the csv file end of the row is only "F" its not returning by the function. When the empty para or the text para is given to the next line of "F", its returned. Why its happening?? is there is any reason...  How to handle this case?



           CSV :





        Empty Next Line (or) next line with contents:

      function readFiles(filStr,fileFlag,column1,column2,column3,column4,columnArr){

          var readFil = File(filStr);

          var rCnt = 0;


              return false;


              var fileContnts = "";


              if(fileFlag == "TXT"){

                  fileContnts = readFil.read();







                          var csvR = zRead.split(",");

                          if(rCnt != 0){








                      rCnt = 1;

          Collect the concept from here:


          var myFile = File.openDialog("Choose a tab delimitted txt file:"); 

          if (!myFile){exit();}      


          var myArray = []  


          while (myFile.eof==false){ 

              var line=myFile.readln().split(",");

            Hi Sudha,


            The issue with your code is that you are using readln and since it reads lines demarcated by newline and the last line does not have a new line after it, that line is skipped.


            A better way would be to read the whole file into a string and then split it up on new line character, something like mentioned below.

            var f = new File("Path to your file")
            var c = f.read()
            var a = c.split("\n")     //In case the line ends with a new line character you will have a blank line in the last entry. Check it and purge it


            Hope this helps

                   Is there is any reason behind the end character is "F"? Because if i append any character with that without any other changes its returning that row contents.  How it is??

                   If its the reason, it should not return the last row contents know? is it right??

                You mean to say this new screenshot that you pasted reads all the lines using readln even if the last line is not terminated by a new line? If so send me the file i can have a look
