• 一、安裝依賴
• 二、template中
• 三、script中程式碼

以將此Excel匯出為json資料為例

一、安裝依賴

npm install file-saver --save
npm install xlsx --save
npm install script-loader --save-dev

二、template中

<span>匯入表格</span>
<input id="upload" type="file" @change="importfxx()"  accept=".csv,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/vnd.ms-excel" />

三、script中js程式碼

methods:{
   // 處理匯入Excel中日期問題
    formatDate(numb,format) {
      const time = new Date((numb - 1) * 24 * 3600000 + 1);
      time.setYear(time.getFullYear() - 70);
      const year = time.getFullYear() + "";
      const month = time.getMonth() + 1 + "";
      const date = time.getDate() - 1 + "";
      if (format && format.length === 1) {
        return year + format + month + format + date;
      }
      return (
        year +
        (month < 10 ? "0" + month : month) +
        (date < 10 ? "0" + date : date)
      );
    },// 匯入Excel
    importfxx() {
      le
 
t _this = this;
      let f = event.currentTarget.files[0];
      let rABS = false; //是否將檔案讀取為二進位制字串

      let reader = new FileReader();
      //if (!FileReader.prototype.readAsBinaryString) {
      FileReader.prototype.readAsBinaryString = function (f) {
        let binary = "";
        let rABS = false; //是否PwYEhHmKYs
 
將檔案讀取為二進位制字串
        let wb; //讀取完成的資料
        let outdata;
        let reader = new FileReader();
        reader.onload = function (e) {
          let bytes = new Uint8Array(reader.result);
          let length = bytes.byteLength;
          for (let i = 0; i < length; i++) {
            binary += String.fromCharCode(bytes[i]);
          }
          let XLSX = require("xlsx");
          if (rABS) {
            wb = XLSX.read(btoa(fixdata(binary)),{
              //手動轉化
              type: "base64",});
          } else {
            wb = XLSX.read(binary,{
              type: "binary",});
          }
          outdata = XLSXPwYEhHmKYs.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]); //outdata就是你想要的東西

          const keyObj = {
            序號: "id",           情況跟蹤: "track",日期: "date",標題: "title",狀態: "status",結果: "result",預警: "warning",};

          outdata.forEach((item) => {
            // 將中文的鍵名替換成英文的
            for (let k in keyObj) {
              let newKey = keyObj[k];
              if (newKey) {
                item[newKey] = item[k];
                delete item[k];
              }
            }
            item["date"] = _this.formatDate(item["date"],"-");
          });
          console.log(outdata);
        };
        reader.readAsArrayBuffer(f);
      };
      if (rABS) {
        reader.readAsArrayBuffer(f);
      } else {
        reader.readAsBinaryString(f);
      }
    },}

如上操作之後，列印結果是如下
