FileReader to String

Consider the following code

function readSingleFile(evt) {
    //Retrieve the first (and only!) File from the FileList object
    var myFile = evt.target.files[0];
    var reader = new FileReader();
    reader.readAsText(myFile);
    var myString = reader.toString();
    alert(myString); // print  - "[object FileReader]"   
}

I try to get all the file content into String , for example if the file content is

helloWorld1
helloWorld2

I will get alert of that's content .

That's not how you get the result of a FileReader. Modify your code to this:

function readSingleFile(evt) {
        //Retrieve the first (and only!) File from the FileList object
        var myFile = evt.target.files[0];
        var reader = new FileReader();
        reader.readAsText(myFile);
        reader.onload=function(){alert(reader.result)}
    }
