How to read excel files using plain javascript

Question

I am trying to display excel sheet data in table format in web page. Currently I am able to read excel data from text area using following code

  function generateTable() {
      var data = $('textarea[name=excel_data]').val();
      console.log(data);
      var rows = data.split("\n");

      var table = $('<table />');

      for(var y in rows) {
          var cells = rows[y].split("\t");
          var row = $('<tr />');
          for(var x in cells) {
              row.append('<td>'+cells[x]+'</td>');
          }
          table.append(row);
      }

      // Insert into DOM
      $('#excel_table').html(table);
      }

Currently I have paste excel file into text area How can I modify above code so that I can directly select the excel file and display it without use of text area. I know solution using angular js or jquery. Can someone tell how to do it using plain javascript

在类似的情况下，请求业务部门将他们的电子表格导出为 .csv 文件比开发解析 .xlsx 的解决方案更容易。
