如何在Javascript/HTML5中解析Excel(XLS)文件

问题描述：

我可以通过FileReader读取Excel文件，但是它可以输出文本以及奇怪的字符.我需要逐行读取xls文件，读取每一列中的数据并将其转换为JSON.

I am able to read Excel file via FileReader but it outputs text as well as weird characters with it. I need to read xls file row-wise, read data in every column and convert it to JSON.

以下功能将Excel工作表(XLSX格式)数据转换为JSON.您可以向函数添加promise.

Below Function converts the Excel sheet (XLSX format) data to JSON. you can add promise to the function.

<script src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.8.0/jszip.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.8.0/xlsx.js"></script>
<script>
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);
  };
};
</script>
