Hi I’am loading a .txt file, it has a lot of data, each line has 16 values and i need to read separetly each colum and store in a variable.
Here is what i have try’d

let year;
let data;

function preload(){
  data = loadStrings("data/FDR.txt");
}
function setup() {
  createCanvas(1400, 700);

//with that i have each inf in a string
  let str = join(data, ' ');
  let words = split(data, ' ');
  

  for(let i =0 ; i<words.length ; i+16){
    year = words[i];
  }
  console.log(year);
}

Sample of the file:
