如何在客户端将数据导出并下载为有效的xlsx格式？

// 假设你已经有了要导出的数据，存储在一个名为data的数组中

// 导出为xlsx格式
const workbook = XLSX.utils.book_new();
const worksheet = XLSX.utils.json_to_sheet(data);
XLSX.utils.book_append_sheet(workbook, worksheet, "Sheet1");
const xlsxFile = XLSX.write(workbook, { bookType: "xlsx", type: "array" });

// 创建下载链接
const blob = new Blob([xlsxFile], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
const url = URL.createObjectURL(blob);

// 创建下载按钮或链接
const downloadLink = document.createElement("a");
downloadLink.href = url;
downloadLink.download = "data.xlsx";
downloadLink.innerHTML = "Download";

// 将下载按钮或链接添加到页面中
document.body.appendChild(downloadLink);
