A number of services host older versions of the SheetJS libraries. Due to
|
|
syncing issues, they are generally out of date.
|
|
|
|
**The SheetJS CDN** https://cdn.sheetjs.com/ **is the authoritative source**
|
|
**for SheetJS scripts**
|

## Browser Scripts
|
|
|
|
`xlsx.full.min.js` is the complete standalone script. It includes support for
|
|
reading and writing many spreadsheet formats.
|
|
|
|
<CodeBlock language="html">{`\
|
|
<!-- use xlsx.full.min.js from version ${current} -->
|
|
<script lang="javascript" src="https://cdn.sheetjs.com/xlsx-${current}/package/dist/xlsx.full.min.js"></script>`}
|
|
</CodeBlock>
|
|
|
|
`xlsx.mini.min.js` is a slimmer build that omits the following features:
|
|
|
|
- CSV and SYLK encodings (directly affecting users outside of the United States)
|
|
- XLSB / XLS / Lotus 1-2-3 / SpreadsheetML 2003 / Numbers file formats
|
|
- [Stream utility functions](/docs/api/stream)
|
|
|
|
<details>
|
|
<summary><b>How to integrate the mini build</b> (click to show)</summary>
|
|
|
|
Replace references to `xlsx.full.min.js` with `xlsx.mini.min.js`. Starting from
|
|
scratch, a single script tag should be added at the top of the HTML page:
|
|
|
|
<CodeBlock language="html">{`\
|
|
<!-- use xlsx.mini.min.js from version ${current} -->
|
|
<script lang="javascript" src="https://cdn.sheetjs.com/xlsx-${current}/package/dist/xlsx.mini.min.js"></script>`}
|
|
</CodeBlock>
|
|
|
|
</details>
|
|
|
|
### Vendoring
|
|
|
|
For general stability, making a local copy of SheetJS scripts ("vendoring") is
|
|
strongly recommended. Vendoring decouples websites from SheetJS infrastructure.
|
|
|
|
<ol start="1"><li><p>Download the script (<code parentName="pre">xlsx.full.min.js</code>) for
|
|
the desired version. The current version is available at <a href={"https://cdn.sheetjs.com/xlsx-" + current + "/package/dist/xlsx.full.min.js"}>{"https://cdn.sheetjs.com/xlsx-" + current + "/package/dist/xlsx.full.min.js"}</a></p></li></ol>
|
|
|
|
2) Move the script to a `public` folder with other scripts.
|
|
|
|
3) Reference the local script from HTML pages:
|
|
|
|
```html
|
|
<script src="/public/xlsx.full.min.js"></script>
|
|
```
|
|
|
|
This script assigns to `window.XLSX`. The global can be used in other scripts.
|
|
|
|
### Internet Explorer and Older Browsers
|
|
|
|
For broad compatibility with JavaScript engines, the library is written using
|
|
ECMAScript 3 language dialect. A "shim" script provides implementations of
|
|
functions for older browsers and environments.
|
|
|
|
Due to SSL compatibility issues, older versions of IE will not be able to
|
|
use the CDN scripts directly. They should be downloaded and saved to a public
|
|
directory in the site:
|
|
|
|
<ul>
|
|
<li>Standalone: <a href={"https://cdn.sheetjs.com/xlsx-" + current + "/package/dist/xlsx.mini.min.js"}>{"https://cdn.sheetjs.com/xlsx-" + current + "/package/dist/xlsx.mini.min.js"}</a></li>
|
|
<li>Shim: <a href={"https://cdn.sheetjs.com/xlsx-" + current + "/package/dist/shim.min.js"}>{"https://cdn.sheetjs.com/xlsx-" + current + "/package/dist/shim.min.js"}</a></li>
|
|
</ul>
|
|
|
|
A `script` reference to the shim must be added before the standalone script:
|
|
|
|
```html
|
|
<!-- add the shim first -->
|
|
<script type="text/javascript" src="shim.min.js"></script>
|
|
<!-- after the shim is referenced, add the library -->
|
|
<script type="text/javascript" src="xlsx.full.min.js"></script>
|
|
```
|
|
|
|
### Web Workers
|
|
|
|
The standalone scripts can be loaded using `importScripts` at the top of the
|
|
worker scripts:
|
|
|
|
<CodeBlock language="js">{`\
|
|
importScripts("https://cdn.sheetjs.com/xlsx-${current}/package/dist/shim.min.js");
|
|
importScripts("https://cdn.sheetjs.com/xlsx-${current}/package/dist/xlsx.full.min.js");`}
|
|
</CodeBlock>
|
|
|
|
|
|
## ECMAScript Module Imports
|
|
|
|
:::caution pass
|
|
|
|
This section refers to imports in HTML pages using `script type="module"`.
|
|
|
|
The ["Frameworks and Bundlers"](/docs/getting-started/installation/frameworks)
|
|
section covers imports in projects using bundlers (ViteJS) or frameworks
|
|
(Kaioken / ReactJS / Angular / VueJS / Svelte)
|
|
|
|
:::
|
|
|
|
The ECMAScript Module build is saved to `xlsx.mjs` and can be directly added to
|
|
a page with a `script` tag using `type="module"`:
|
|
|
|
<CodeBlock language="html">{`\
|
|
<script type="module">
|
|
import { read, writeFileXLSX } from "https://cdn.sheetjs.com/xlsx-${current}/package/xlsx.mjs";
|
|
</script>`}
|
|
</CodeBlock>
|
|
|
|
If Encoding support is required, `cpexcel.full.mjs` must be manually imported:
|
|
|
|
<CodeBlock language="html">{`\
|
|
<script type="module">
|
|
/* load the codepage support library for extended support with older formats */
|
|
import { set_cptable } from "https://cdn.sheetjs.com/xlsx-${current}/package/xlsx.mjs";
|
|
import * as cptable from 'https://cdn.sheetjs.com/xlsx-${current}/package/dist/cpexcel.full.mjs';
|
|
set_cptable(cptable);
|
|
</script>`}
|
|
</CodeBlock>
|
|
|
|
Web Worker support is noted in [the "Web Workers" demo](/docs/demos/bigdata/worker#installation)
|
|
|
|
### Dynamic Imports
|
|
|
|
Dynamic imports with `import()` will only download the SheetJS scripts when they
|
|
are used. This example will download the library when data is exported:
|
|
|
|
<CodeBlock language="html">{`\
|
|
<button id="xport">Export</button>
|
|
<script type="module">
|
|
xport.addEventListener("click", async() => {
|
|
\n\
|
|
/* dynamically import the script in the event listener */
|
|
// highlight-next-line
|
|
const XLSX = await import("https://cdn.sheetjs.com/xlsx-${current}/package/xlsx.mjs");
|
|
\n\
|
|
const wb = XLSX.utils.book_new();
|
|
const ws = XLSX.utils.aoa_to_sheet([["a","b","c"],[1,2,3]]);
|
|
XLSX.utils.book_append_sheet(wb, ws, "Sheet1");
|
|
XLSX.writeFile(wb, "SheetJSESMTest.xlsx");
|
|
});
|
|
</script>`}
|
|
</CodeBlock>
|
|
|
|
:::caution pass
|
|
|
|
The callback functions must be marked as `async` and the script block must have
|
|
the attribute `type="module"`
|
|
|
|
:::
|
|
|
|
If Encoding support is required, `cpexcel.full.mjs` must be manually imported:
|
|
|
|
<CodeBlock language="html">{`\
|
|
<button id="xport">Export</button>
|
|
<script type="module">
|
|
xport.addEventListener("click", async() => {
|
|
\n\
|
|
/* dynamically import the scripts in the event listener */
|
|
// highlight-start
|
|
const XLSX = await import("https://cdn.sheetjs.com/xlsx-${current}/package/xlsx.mjs");
|
|
const cptable = await import("https://cdn.sheetjs.com/xlsx-${current}/package/dist/cpexcel.full.mjs");
|
|
XLSX.set_cptable(cptable);
|
|
// highlight-end
|
|
\n\
|
|
const wb = XLSX.utils.book_new();
|
|
const ws = XLSX.utils.aoa_to_sheet([["a","b","c"],[1,2,3]]);
|
|
XLSX.utils.book_append_sheet(wb, ws, "Sheet1");
|
|
XLSX.writeFile(wb, "SheetJSESMTest.xlsx");
|
|
});
|
|
</script>`}
|
|
</CodeBlock>
|
|
|
|
## Bower
|
|
|
|
:::danger pass
|
|
|
|
Bower is deprecated and the maintainers recommend using other tools.
|
|
|
|
:::
|
|
|
|
The Bower package manager supports tarballs from the SheetJS CDN:
|
|
|
|
<CodeBlock language="bash">{`\
|
|
npx bower install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
|
|
</CodeBlock>
|
|
|
|
Bower will place the standalone scripts in `bower_components/js-xlsx/dist/`
|
