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 </details> With [bower](https://bower.io/search/?q=js-xlsx): ```bash $ bower install js-xlsx ``` **ECMAScript Modules** The ECMAScript Module build is saved to `xlsx.mjs` and can be directly added to a page with a `script` tag using `type=module`: ```html <script type="module"> import { read, writeFileXLSX } from "./xlsx.mjs"; /* load the codepage support library for extended support with older formats */ import { set_cptable } from "./xlsx.mjs"; import * as cptable from './dist/cpexcel.full.mjs'; set_cptable(cptable); </script> ``` The [npm package](https://www.npmjs.org/package/xlsx) also exposes the module with the `module` parameter, supported in Angular and other projects: ```ts import { read, writeFileXLSX } from "xlsx"; /* load the codepage support library for extended support with older formats */ import { set_cptable } from "xlsx"; import * as cptable from 'xlsx/dist/cpexcel.full.mjs'; set_cptable(cptable); ``` **Deno** `xlsx.mjs` can be imported in Deno. It is available from `unpkg`: ```ts // @deno-types="https://unpkg.com/xlsx/types/index.d.ts" import * as XLSX from 'https://unpkg.com/xlsx/xlsx.mjs'; /* load the codepage support library for extended support with older formats */ import * as cptable from 'https://unpkg.com/xlsx/dist/cpexcel.full.mjs'; XLSX.set_cptable(cptable); ``` **NodeJS** With [npm](https://www.npmjs.org/package/xlsx): ```bash $ npm install xlsx ``` By default, the module supports `require`: ```js var XLSX = require("xlsx"); ``` The module also ships with `xlsx.mjs` for use with `import`: ```js import * as XLSX from 'xlsx/xlsx.mjs'; /* load 'fs' for readFile and writeFile support */ import * as fs from 'fs'; XLSX.set_fs(fs); /* load 'stream' for stream support */ import { Readable } from 'stream'; XLSX.stream.set_readable(Readable); /* load the codepage support library for extended support with older formats */ import * as cpexcel from 'xlsx/dist
