如何在同一個excel文件中將數據分隔到新工作表

Question

如果我在array2D中有數據，我想將每個設備分開到excel文件中的每個工作表。 從我下面的代碼這里我需要更改exportToCSV（）來解決這個問題。

const rows = [
  ["DeviceA"]
  ["Date/Time", "smokeSensor", "fireSensor"],
  ["190501 00:01", "200", "700"],
  ["190501 00:02", "300", "750"],
  ["190502 00:01", "20", "780"],
  ["190502 00:02", "30", "630"],
  [""],
  ["DeviceB"],
  ["Date/Time", "smokeSensor", "fireSensor"],
  ["190501 00:01", "100", "600"],
  ["190501 00:02", "110", "522"],
  ["190502 00:01", "120", ""],
  ["190502 00:02", "130", ""],
];

function exportToCSV(rows) {
      let csvContent = ""
      rows.forEach(function(rowArray) {
          let row = rowArray.join(",")
          csvContent += row + "\r\n"
      });
      var link = document.createElement("a")
      document.body.appendChild(link)
      // var blob = new Blob([csvContent], {type: "text/csv"}); 
      var blob = new Blob([csvContent], {type: "xls/xlsx"})
      var url = window.URL.createObjectURL(blob)
      link.setAttribute("href", url)
      link.setAttribute("download", "my_data.csv")
      link.click() /* Download the data file named "my_data.csv". */
}

Answer 1

CSV不支持在工作表中分離數據。

我創建了一個名為ExcellentExport的JavaScript庫，用於將表或數組導出為CSV或Excel。

excel導出支持工作表：

ExcellentExport.convert({ anchor: this, filename: 'data_123.array', format: 'xlsx'}, [
    {name: 'Sheet Name Here 1', from: {array: yourArray1}},
    {name: 'Sheet 2', from: {array: yourArray2}},
]);

對於CSV解析，您可以使用Papa Parse。 您可以將CSV解析為JSON並執行操作，您可以再次從JSON解析為CSV
