### Optional Modules

<details>
  <summary><b>Optional features</b> (click to show)</summary>

The node version automatically requires modules for additional features.  Some
of these modules are rather large in size and are only needed in special
circumstances, so they do not ship with the core.  For browser use, they must
be included directly:

```html
<!-- international support from js-codepage -->
<script src="dist/cpexcel.js"></script>
```

An appropriate version for each dependency is included in the dist/ directory.

The complete single-file version is generated at `dist/xlsx.full.min.js`

Webpack and Browserify builds include optional modules by default.  Webpack can
be configured to remove support with `resolve.alias`:

```js
  /* uncomment the lines below to remove support */
  resolve: {
    alias: { "./dist/cpexcel.js": "" } // <-- omit international support
  }
```

</details>

### ECMAScript 5 Compatibility

Since the library uses functions like `Array#forEach`, older browsers require
[shims to provide missing functions](http://oss.sheetjs.com/js-xlsx/shim.js).

To use the shim, add the shim before the script tag that loads `xlsx.js`:

```html
<!-- add the shim first -->
<script type="text/javascript" src="shim.js"></script>
<!-- after the shim is referenced, add the library -->
<script type="text/javascript" src="xlsx.full.min.js"></script>
```
