Hello everyone,

Have a simple one here, had it working last night. Didn't save it and lost power, my dumb mistake. I have had to start from scratch again and keep getting the error above.

I am trying to load a text file and clean it up to remove the whitespace. Not sure why I keep getting the "Cannot convert String to String[]". Obviously not the best coder but I'm getting better. I'm sure it something simple that I am missing.

Thanks to all.

Code:

void setup() {
  String[] lotteryRaw = loadStrings("lottery") ;
  int numLines = lotteryRaw.length;
  println(numLines + " lines of data loaded");
  println("Starting parse...");
  parse(lotteryRaw);
  
}

void parse(String[] lotteryRaw) {
  for (int i = 0; i < lotteryRaw.length; i++) {
    String[] clean = lotteryRaw[i].replaceAll("\\W", "") ;
    println(clean[i]);
  } 
}  

Awesome,

Thanks for the help, I knew it was something simple. It's amazing how at 3am the magic just flows, but in the afternoon it's a struggle.

Thanks again.
