浏览器把JSON导出转为excel下载到本地
Author：[email protected] Date：
JSON to excel文件下载，npm包搜了一下https://www.npmjs.com/search?q=json%20to%20excel
最近选择xlxs库，看官方代码：https://docs.sheetjs.com/docs/getting-started/example/
<body>
<script src="https://cdn.sheetjs.com/xlsx-latest/package/dist/xlsx.full.min.js"></script>
<script>
(async() => {
/* fetch JSON data and parse */
/* flatten objects */
const rows = [
{
"COUNT(create_by)": 41,
"COUNT(DISTINCT biz_id)": 1,
"biz_id": "-1",
"_unique_metric_": "-1"
},
{
"COUNT(create_by)": 1564,
"COUNT(DISTINCT biz_id)": 1,
"biz_id": "100140",
"_unique_metric_": "100140"
},
];
/* generate worksheet and workbook */
const worksheet = XLSX.utils.json_to_sheet(rows);
const workbook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(workbook, worksheet, "Dates");
/* create an XLSX file and try to save to Presidents.xlsx */
XLSX.writeFile(workbook, "Presidents.xlsx", { compression: true });
})();
</script>
<body>是可以的，但是本地无法加载，发现报：typescript referenceError: require is not defined
他们的，发现npm i 直接安装不行，
只有这样才可以：
npm i --save https://cdn.sheetjs.com/xlsx-0.19.3/xlsx-0.19.3.tgz
详情见官方文档：https://docs.sheetjs.com/docs/getting-started/installation/frameworks
xlxs库发现按需加载不行：
import { writeFile, utils } from 'xlsx';不知道如何处理。
详情代码如下
下载文件代码：
// import { writeFile, utils } from 'xlsx';
import XLSX from 'xlsx';
export default function (
rows: Record<string, string>[],
title = `${new Date().getTime()}`,
) {
if (!rows.length) {
return;
}
/* generate worksheet and workbook */
const worksheet = XLSX.utils.json_to_sheet(rows);
const workbook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(workbook, worksheet, 'Dates');
/* create an XLSX file and try to save to Presidents.xlsx */
XLSX.writeFile(workbook, `${title}.xlsx`, { compression: true });
}
