@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(',')));
};
