In the browser, it will try to prompt the user to download the file. In NodeJS,
it will write to the local directory.
:::note
`XLSX.writeFileXLSX` only writes XLSX files and is recommended when the export
will always be in the `.xlsx` format. `writeFileXLSX` is more amenable to tree
shaking. This example uses `XLSX.writeFile` since `writeFileXLSX` does not
support other common export formats like `.xls` or `.xlsb` or `.csv`.
:::
```js
XLSX.writeFile(workbook, "Presidents.xlsx");

## Vite
:::caution
ViteJS adopted nascent `package.json` patterns. Version 0.18.10 implements the
patterns required for ViteJS 3.0.3. These patterns are evolving and a future
version of Vite may require more packaging changes.
:::
ViteJS 3.0.3 is known to work with SheetJS version 0.18.10.
<details><summary><b>Complete Example</b> (click to show)</summary>
1) Create a new ViteJS project:
```
npm create vite@latest
cd sheetjs-vite # (project name)
npm i
```
When prompted for **Project Name**, type **`sheetjs-vite`**
When prompted for **Framework**, select **`vue`** then **`vue-ts`**
2) Add the SheetJS dependency:
<pre><code parentName="pre" {...{"className": "language-bash"}}>{`\
$ npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
</code></pre>
3) Replace `src\components\HelloWorld.vue` with:
```html title="src\components\HelloWorld.vue"
<script setup lang="ts">
import { version, utils, writeFileXLSX } from 'xlsx';
interface President {
terms: { "type": "prez" | "viceprez"; }[];
name: { first: string; last: string; }
bio: { birthday: string; }
}
async function xport() {
/* fetch JSON data and parse */
const url = "https://sheetjs.com/executive.json";
const raw_data: President[] = await (await fetch(url)).json();
/* filter for the Presidents */
const prez = raw_data.filter(row => row.terms.some(term => term.type === "prez"));
/* flatten objects */
const rows = prez.map(row => ({
name: row.name.first + " " + row.name.last,
birthday: row.bio.birthday
}));
/* generate worksheet and workbook */
const worksheet = utils.json_to_sheet(rows);
const workbook = utils.book_new();
utils.book_append_sheet(workbook, worksheet, "Dates");
/* fix headers */
utils.sheet_add_aoa(worksheet, [["Name", "Birthday"]], { origin: "A1" });
/* calculate column width */
const max_width = rows.reduce((w, r) => Math.max(w, r.name.length), 10);
worksheet["!cols"] = [ { wch: max_width } ];
/* create an XLSX file and try to save to Presidents.xlsx */
writeFileXLSX(workbook, "Presidents.xlsx");
}
</script>
<template>
<button type="button" @click="xport">Export with SheetJS version {{ version }}</button>
</template>
```
4) Run `npm run dev` and test functionality by opening a web browser to
http://localhost:5173/ and clicking the button
5) Run `npx vite build` and verify the generated pages work by running a local
web server in the `dist` folder:
```
npx http-server dist/
```
Access http://localhost:8080 in your web browser.
