A Simple Function That Parses a CSV String Into JSON

function parseCSV(str){
 
 
 var csvArr = str.replace(/","/igm,",,,").split("\n");
 //takes input CSV string and replaces all the separators
 //with triple commas to prevent confusion with commas
 //that may be part of a record and not a seperator,
 //then splits at every newline to create an array of records
 
 
 var key = csvArr[0].split(',,,');
 //the key is the first line, which is used to map
 //the other records 
 
 var csvRecords = new Array();
 //main array for storing data
 
 
 csvArr.pop(); 
 (csvArr[csvArr.length-1]) ? csvArr.shift() : false
 //first entry in csvArr is the key, remove it
 //last entry is typically a blank string, remove it
 
 for(var i=0;i<csvArr.length;i++){
  //traverses all valid records in csvArr
  
  csvRecords[i] = { };
  
  var rec = csvArr[i].split(',,,');
  //rec is set anew for each row in the csv file
  
  for(var x=0;x<csvArr[i].length;x++){
   
   csvRecords[i][key[x]] = rec[x];
   //for each row in csvArr, set the obj property
   //to the correct entry from the key array
   //and set the property value to the correct
   //value from rec
  }
 }
 return csvRecords;
 //all done
}
