[Browserify](https://browserify.org/) is a module bundler.
|
||
|
|
|
||
|
|
[SheetJS](https://sheetjs.com) is a JavaScript library for reading and writing
|
||
|
|
data from spreadsheets.
|
||
|
|
|
||
|
|
This demo uses Browserify and SheetJS to export data. We'll explore how to add
|
||
|
|
SheetJS to a site using Browserify and how to export data to spreadsheets.

## Integration Details
|
||
|
|
|
||
|
|
[The "Frameworks" section](/docs/getting-started/installation/frameworks) covers
|
||
|
|
installation with Yarn and other package managers.
|
||
|
|
|
||
|
|
After installing the SheetJS module in a Browserify project, `require`
|
||
|
|
expressions can load relevant parts of the library.
|
||
|
|
|
||
|
|
```js
|
||
|
|
var XLSX = require("xlsx");
|
||
|
|
// ... use XLSX ...
|
||
|
|
```
|
||
|
|
|
||
|
|
Browserify can also process `require` expressions in Web Worker scripts.
|
||
|
|
|
||
|
|
## Complete Example
|
||
|
|
|
||
|
|
0) Initialize a new project:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
mkdir sheetjs-browserify
|
||
|
|
cd sheetjs-browserify
|
||
|
|
npm init -y
|
||
|
|
```
|
||
|
|
|
||
|
|
1) Install the tarball using a package manager:
|
||
|
|
|
||
|
|
<Tabs groupId="pm">
|
||
|
|
<TabItem value="npm" label="npm">
|
||
|
|
<CodeBlock language="bash">{`\
|
||
|
|
npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
|
||
|
|
</CodeBlock>
|
||
|
|
</TabItem>
|
||
|
|
<TabItem value="pnpm" label="pnpm">
|
||
|
|
<CodeBlock language="bash">{`\
|
||
|
|
pnpm install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
|
||
|
|
</CodeBlock>
|
||
|
|
</TabItem>
|
||
|
|
<TabItem value="yarn" label="Yarn" default>
|
||
|
|
<CodeBlock language="bash">{`\
|
||
|
|
yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
|
||
|
|
</CodeBlock>
|
||
|
|
</TabItem>
|
||
|
|
</Tabs>
|
||
|
|
|
||
|
|
2) Save the following to `index.js`:
|
||
|
|
|
||
|
|
```js title="index.js"
|
||
|
|
// highlight-next-line
|
||
|
|
const { utils, version, writeFileXLSX } = require('xlsx');
|
||
|
|
|
||
|
|
document.getElementById("xport").addEventListener("click", function() {
|
||
|
|
/* fetch JSON data and parse */
|
||
|
|
var url = "https://sheetjs.com/data/executive.json";
|
||
|
|
fetch(url).then(function(res) { return res.json(); }).then(function(raw_data) {
|
||
|
|
|
||
|
|
/* filter for the Presidents */
|
||
|
|
var prez = raw_data.filter(function(row) { return row.terms.some(function(term) { return term.type === "prez"; }); });
|
||
|
|
|
||
|
|
/* sort by first presidential term */
|
||
|
|
prez.forEach(function(row) {
|
||
|
|
row.start = row.terms.find(function(term) {
|
||
|
|
return term.type === "prez";
|
||
|
|
}).start
|
||
|
|
});
|
||
|
|
prez.sort(function(l,r) { return l.start.localeCompare(r.start); });
|
||
|
|
|
||
|
|
/* flatten objects */
|
||
|
|
var rows = prez.map(function(row) { return {
|
||
|
|
name: row.name.first + " " + row.name.last,
|
||
|
|
birthday: row.bio.birthday
|
||
|
|
}; });
|
||
|
|
|
||
|
|
/* generate worksheet and workbook */
|
||
|
|
var worksheet = utils.json_to_sheet(rows);
|
||
|
|
var 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 */
|
||
|
|
var max_width = rows.reduce(function(w, r) { return 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");
|
||
|
|
});
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
3) Bundle the scripts:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npx browserify app.js > browserify.js
|
||
|
|
```
|
||
|
|
|
||
|
|
4) Spin up a local web server:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npx http-server
|
||
|
|
```
|
||
|
|
|
||
|
|
5) Create a small HTML page that loads the script. Save to `index.html`:
|
||
|
|
|
||
|
|
```html title="index.html"
|
||
|
|
<!DOCTYPE html>
|
||
|
|
<html lang="en">
|
||
|
|
<head></head>
|
||
|
|
<body>
|
||
|
|
<h1>SheetJS Presidents Demo</h1>
|
||
|
|
<button id="xport">Click here to export</button>
|
||
|
|
<script src="./index.min.js"></script>
|
||
|
|
</body>
|
||
|
|
</html>
|
||
|
|
```
|
||
|
|
|
||
|
|
6) Start a local HTTP server and go to `http://localhost:8080/`
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npx http-server .
|
||
|
|
```
|
||
|
|
|
||
|
|
Click on "Click here to export" to generate a file.
