Usage Guide

Installing

The installation is just a command

After installing the package you can use the "parseCSV" method as follows

 parseCSV("CSV-file-name.csv", callBack)
 //where callBack is a function having the argument data 
 //which is an array structure of the CSV file

Example

 var csv = require('csv-array');
 csv.parseCSV("test.csv", function(data){
   console.log(JSON.stringify(data));
 });

If the test.csv file contains something like this

 Question Statement,Option 1,Option 2,Option 3,Option 4,Option 5,Answer,Deficulty,Category
this is a test question answer it?,answer 1,answer 2,answer3,answer 4,,answer 2,3,test
this is another test question answer it?,"answer1,answer2","answer2,answer3","answer4,answer5","answer5,answer6","answer7,answer8","answer1,answer2",2,test

Then the resulting data is as follows

[  
   {  
      "Question Statement":"this is a test question answer it?",
      "Option 1":"answer 1",
      "Option 2":"answer 2",
      "Option 3":"answer3",
      "Option 4":"answer 4",
      "Option 5":"",
      "Answer":"answer 2",
      "Deficulty":"3"
   },
   {  
      "Question Statement":"this is another test question answer it?",
      "Option 1":"answer1,answer2",
      "Option 2":"answer2,answer3",
      "Option 3":"answer4,answer5",
      "Option 4":"answer5,answer6",
      "Option 5":"answer7,answer8",
      "Answer":"answer1,answer2",
