ok, sorry, yes there is a need to first set the column to NUMBER instead TEXT

i told you the “table” way is just a first idea.
but in this time would easily made your own loadstring // sort array // version
( and possibly would have learned more about loops …)

but usually a csv file has a header ( column name )

example v0.3

// v 0.2 change from tsv to csv
// v 0.2 use col 2 as INT so get a number sort instead a lexical sort
// v 0.3 make header

String infilename  = "data/bookmarks.txt";
String outfilename = "data/bookmarks_sort.txt";
Table mytable;
int tcols, trows, numcol = 2;
boolean dprint = true;


void getf_tabledata() {                             // get tabledata from file
  mytable = loadTable(infilename, "header, csv");
  tcols = mytable.getColumnCount();
  if (dprint) println("total cols in table: "+tcols);
  trows = mytable.getRowCount();
  if (dprint) println("total rows in table: "+trows);
  if (dprint) println("header: ");
  for ( int i =0; i < tcols; i++) {
    if (dprint) println("headerline col: "+i+" "+ mytable.getColumnTitle(i));
  }
}

void sort_tabledata() {                             // sort numerically a specific column
  mytable.setColumnType(numcol, Table.INT); 
  mytable.sort(numcol);  
  if (dprint) println("list all rows column "+numcol+" sorted by number");
  for ( int i = 0; i < mytable.getRowCount(); i++ ) {
    TableRow thisrow = mytable.getRow(i);
    if (dprint) println("row "+i+" "+thisrow.getInt(numcol));
  }
}

void save_tabledata() {                             // save to other file
  saveTable(mytable, outfilename, "csv");
}

void setup() {
  getf_tabledata();
  sort_tabledata();
  save_tabledata();
  exit();
}
