EN

var ExcelToJSON = function() {

  this.parseExcel = function(file) {
    var reader = new FileReader();

    reader.onload = function(e) {
      var data = e.target.result;
      var workbook = XLSX.read(data, {
        type: 'binary'
      });

      workbook.SheetNames.forEach(function(sheetName) {
        // Here is your object
        var XL_row_object = XLSX.utils.sheet_to_row_object_array(workbook.Sheets[sheetName]);
        var json_object = JSON.stringify(XL_row_object);
        console.log(json_object);

      })

    };

    reader.onerror = function(ex) {
      console.log(ex);
    };

    reader.readAsBinaryString(file);
  };
};

var ExcelToJSON = function() {

      this.parseExcel = function(file) {
        var reader = new FileReader();

        reader.onload = function(e) {
          var data = e.target.result;
          var workbook = XLSX.read(data, {
            type: 'binary'
          });
          workbook.SheetNames.forEach(function(sheetName) {
            // Here is your object
            var XL_row_object = XLSX.utils.sheet_to_row_object_array(workbook.Sheets[sheetName]);
            var json_object = JSON.stringify(XL_row_object);
            console.log(JSON.parse(json_object));
            jQuery( '#xlx_json' ).val( json_object );
          })
        };

        reader.onerror = function(ex) {
          console.log(ex);
        };

        reader.readAsBinaryString(file);
      };
  };

  function handleFileSelect(evt) {
    
    var files = evt.target.files; // FileList object
    var xl2json = new ExcelToJSON();
    xl2json.parseExcel(files[0]);
  }


 



    


    

    
        document.getElementById('upload').addEventListener('change', handleFileSelect, false);
