Due to syncing issues, they are generally out of date. They are known CDN bugs. is the authoritative source for SheetJS modules. ::: ## Browser Scripts `xlsx.full.min.js` is the complete standalone script. It includes support for reading and writing many spreadsheet formats.
{`\

`}
A slimmer build is generated at `dist/xlsx.mini.min.js`. Compared to full build: - codepage library skipped (no support for XLS encodings) - no support for XLSB / XLS / Lotus 1-2-3 / SpreadsheetML 2003 / Numbers - node stream utils removed
How to integrate the mini build (click to show) 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:
{`\

`}
### 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:
Add a `script` reference to the shim before the script tag that loads `xlsx.js`: ```html ``` ### Web Workers The standalone scripts can be loaded using `importScripts` at the top of the worker scripts:
{`\
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");`}
## ECMAScript Module Imports :::caution This section refers to imports using `script type="module"`. For imports in modern projects using Webpack or React or Angular or VueJS, the installation is described [in the next section](/docs/getting-started/installation/frameworks). ::: The ECMAScript Module build is saved to `xlsx.mjs` and can be directly added to a page with a `script` tag using `type="module"`:
{`\
`}
If Encoding support is required, `cpexcel.full.mjs` must be manually imported:
{`\
`}
Dynamic imports with `import()` can be used in data export scenarios. This example will download the library only when the export button is pressed:
{`\

`}
Web Worker support is noted in [the demo](/docs/demos/worker#installation) ## Bower :::caution Bower is deprecated and the maintainers recommend using other tools. ::: The Bower package manager plays nice with the CDN tarballs:
{`\
npx bower install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
Bower will place the standalone scripts in `bower_components/js-xlsx/dist/`
