How to read files .csv very big with FileReader API javascript, html/jquery only

Question

I'm trying to read a file .csv over 40 MB (with more 20.000 lines), viewing it as a table in html. The system I am designing will be in pure HTML + JQuery only. My worksheet .csv format that is:

=======================================================================
| rank ||  place           || population ||    lat    ||      lon     |
=======================================================================
|  1   || New York city    ||  8175133   || 40.71455  ||  -74.007124  |
-----------------------------------------------------------------------
|  2   || Los Angeles city ||  3792621   || 34.05349  ||  -118.245323 |
-----------------------------------------------------------------------
..........................Thousands of lines..........................

I have a textbox filter that makes me just showing the line that has the same number entered in the field. I have a textbox filter that makes me just showing the line that has the same number entered in the field. And then uploading the file it breaks the browser. :( Follow my code:

var fileInput = document.getElementById('fileInput');
var fileDisplayArea = document.getElementById('fileDisplayArea');

        fileInput.addEventListener('change', function(e) {
            var file = fileInput.files[0];

                var reader = new FileReader();

                reader.onload = function(e) {

                    //Convert .csv to table html
                    var data = reader.result; 
                    var rank = $("#rank").val(); 

                    if(rank == ""){
                        alert("digit rank number");
                        fileInput.value = "";
                     }
                     else{



                    data = data.replace(/\s/, " #"); 
                    data = data.replace(/([0-9]\s)/g, "$1#"); 
                    var lines = data.split("#"), 
                        output = [],
                        i;
                        for (i = 0; i < lines.length; i++)
                        output.push("<tr><td>" + lines[i].slice(0,-1).split(",").join("</td><td>") + "</td></tr>");
                        output = "<table>" + output.join("") + "</table>";

var valuefinal = $(output).find('tr').filter(function(){ 
    return $(this).children('td').eq(0).text() == rank;
});

 $('#fileDisplayArea').append(valuefinal);

                     }
                }

                reader.readAsBinaryString(file);    


        });

Is it possible to do something that I optimize my code and not let my browser and break my file to be read? I tried to split the file into pieces and then seal it. (BLOB) But this way he kept crashing my browser too. :(

As I found this thread on my research to parse a very big CSV file in the parser, I wanted to add that my final solution was to use Papa Parse:
