如何在sapui5中将csv文件转换为xls或xlsx？

// 导入所需的库
sap.ui.define([
  "sap/ui/core/mvc/Controller",
  "sap/ui/model/json/JSONModel",
  "sap/m/MessageToast"
], function(Controller, JSONModel, MessageToast) {
  "use strict";

  return Controller.extend("your.controller.name", {
    onInit: function() {
      // 创建FileUploader控件
      var oFileUploader = new sap.ui.unified.FileUploader({
        uploadComplete: this.onUploadComplete.bind(this)
      });

      // 将FileUploader添加到视图中
      this.getView().byId("fileUploaderContainer").addItem(oFileUploader);
    },

    onUploadComplete: function(oEvent) {
      var oFile = oEvent.getParameter("files")[0];
      var oFileReader = new FileReader();

      oFileReader.onload = function(e) {
        var sCSVData = e.target.result;

        // 使用PapaParse解析CSV数据
        var oParsedData = Papa.parse(sCSVData, {
          header: true
        });

        // 创建Excel工作簿
        var oWorkbook = XLSX.utils.book_new();
        var oWorksheet = XLSX.utils.json_to_sheet(oParsedData.data);
        XLSX.utils.book_append_sheet(oWorkbook, oWorksheet, "Sheet1");

        // 将工作簿保存为XLSX文件
        var sXLSXPath = XLSX.writeFile(oWorkbook, "output.xlsx");

        // 显示下载链接
        MessageToast.show("转换完成！下载链接：" + sXLSXPath);
      };

      oFileReader.readAsText(oFile);
    }
  });
});
