Convert String Array to int / float (loadStrings)

technically, you could make a 2D array (grid, see tutorials) of float, because you have

  • a lot of lines and
  • each of them contains several (different numbers of!) floats.

Remark

I looked at your csv and the 2nd line is VERY long.
You posted only 2 lines.

Here is my Sketch

Here is my Sketch. It’s like in the description above.
It splits each line (all lines) and shows each float “zahl” within the line.

//
String [] lines; 

void setup() {
  size (800, 600);

  lines = loadStrings("numbers.csv");
  println("length is "
    +lines.length);
}

void draw() {
  // when opening window background is black
  background(0);
}

void mousePressed() {

  // when mousePressed 

  // iterate over Array 
  for (String n : lines) {

    // split line
    String[] thisLine = n.split (","); 

    // loop over line
    for (String n2 : thisLine) {
      // convert to float
      float zahl = float(n2);
      print(zahl);
      print(" ");
    }//for 
    println("\n\n");
  } //for
  //
} //func
