is there way browse file user , accept value in 5th,6th,7th field of .txt file.

to file uploaded check out kk anu's answer.

once have file in access , can read it, it's straight forward iteration of each line.

var linesfromfile= file.split(/[ ,]+/);  linesfromfile.foreach(function(entry) {     var parsedfloat = parsefloat(entry);      if(parsedfloat === number(parsedfloat)  && parsedfloat%1!==0){         // parsed float     } });

you have adapt code needs, function go with.
