CSV to JSON Conversion in JavaScript

csv-to-json.js

//var csv is the CSV file with headers
function csvJSON(csv){

  var lines=csv.split("\n");

  var result = [];

  var headers=lines[0].split(",");

  for(var i=1;i<lines.length;i++){

	  var obj = {};
	  var currentline=lines[i].split(",");

	  for(var j=0;j<headers.length;j++){
		  obj[headers[j]] = currentline[j];
	  }

	  result.push(obj);

  }
  
  //return result; //JavaScript object
  return JSON.stringify(result); //JSON
}

@OFRBG I liked this your solution. I suggest just filtering the lines before iteration to eliminate blank lines from the csv file.

const csvToJson = csv => {
  const [firstLine, ...lines] = csv.split('\n');
  const keys = firstLine.split(',');
  // add a filter here
  return lines.filter(line => line).map(line => ((values) => 
    keys.reduce(
      (curr, next, index) => ({
        ...curr,
        [next]: values[index],
      }),
      {}
    )
  )(line.split(',')));
};
