Getting Started

Installation

Standalone Browser Scripts

The complete browser standalone build is saved to dist/xlsx.full.min.js and can be directly added to a page with a script tag:

<script lang="javascript" src="dist/xlsx.full.min.js"></script>

CDN Availability (click to show)

CDN	URL
unpkg	https://unpkg.com/xlsx/

For example, unpkg makes the latest version available at:

<script src="https://unpkg.com/xlsx/dist/xlsx.full.min.js"></script>

Browser builds (click to show)

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

dist/xlsx.core.min.js omits codepage library (no support for XLS encodings)

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

With bower:

$ 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:

<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 also exposes the module with the module parameter, supported in Angular and other projects:

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

The sheetjs package is hosted by Deno:

// @deno-types="https://deno.land/x/sheetjs/types/index.d.ts"
import * as XLSX from 'https://deno.land/x/sheetjs/xlsx.mjs'

/* load the codepage support library for extended support with older formats  */
import * as cptable from 'https://deno.land/x/sheetjs/dist/cpexcel.full.mjs';
XLSX.set_cptable(cptable);

NodeJS

With npm:

$ npm install xlsx

By default, the module supports require:

var XLSX = require("xlsx");

The module also ships with xlsx.mjs for use with import:

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/cpexcel.full.mjs';
XLSX.set_cptable(cpexcel);

Photoshop and InDesign

dist/xlsx.extendscript.js is an ExtendScript build for Photoshop and InDesign that is included in the npm package. It can be directly referenced with a #include directive:

#include "xlsx.extendscript.js"

Internet Explorer and ECMAScript 3 Compatibility (click to show)

For broad compatibility with JavaScript engines, the library is written using ECMAScript 3 language dialect as well as some ES5 features like Array#forEach. Older browsers require shims to provide missing functions.

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

<!-- 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>

The script also includes IE_LoadFile and IE_SaveFile for loading and saving files in Internet Explorer versions 6-9. The xlsx.extendscript.js script bundles the shim in a format suitable for Photoshop and other Adobe products.
