Answer

Here is a small sample that creates 2 sheets.

Just use book_append_sheet function

var ws_data = [
  ["Column 1"],
  [1]
];
var ws = XLSX.utils.aoa_to_sheet(ws_data);


var ws_data2 = [
  ["Column 2"],
  [2]
];
var ws2 = XLSX.utils.aoa_to_sheet(ws_data2);

const wb = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(wb, ws, "SheetJS1");
XLSX.utils.book_append_sheet(wb, ws2, "SheetJS2");

XLSX.writeFile(wb, "sheetjs.xlsx");
