Getting Started

Installation

Standalone Browser Scripts

Each standalone release script is available at https://cdn.sheetjs.com/.

The current version is 0.18.7 and can be referenced as follows:

<!-- use version 0.18.7 -->
<script lang="javascript" src="https://cdn.sheetjs.com/xlsx-0.18.7/package/dist/xlsx.full.min.js"></script>

The latest tag references the latest version and updates with each release:

<!-- use the latest version -->
<script lang="javascript" src="https://cdn.sheetjs.com/xlsx-latest/package/dist/xlsx.full.min.js"></script>

For production use, scripts should be downloaded and added to a public folder alongside other scripts.

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

These scripts are also available on the CDN:

<!-- use xlsx.mini.min.js from version 0.18.7 -->
<script lang="javascript" src="https://cdn.sheetjs.com/xlsx-0.18.7/package/dist/xlsx.mini.min.js"></script>

Bower will pull the entire repo:

$ bower install js-xlsx

Bower will place the standalone scripts in bower_components/js-xlsx/dist/

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>

Due to SSL certificate compatibility issues, it is highly recommended to save the Standalone and Shim scripts from https://cdn.sheetjs.com/ and add to a public directory in the site.

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.

ECMAScript Modules

Browser ESM

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 "https://cdn.sheetjs.com/xlsx-0.18.7/package/xlsx.mjs";

/* load the codepage support library for extended support with older formats  */
import { set_cptable } from "https://cdn.sheetjs.com/xlsx-0.18.7/package/xlsx.mjs";
import * as cptable from 'https://cdn.sheetjs.com/xlsx-0.18.7/package/dist/cpexcel.full.mjs';
set_cptable(cptable);
</script>

Frameworks (Angular, VueJS, React) and Bundlers (webpack, etc)

The NodeJS package is readily installed from the tarballs:

$ npm  install --save https://cdn.sheetjs.com/xlsx-0.18.7/xlsx-0.18.7.tgz # npm
$ pnpm install --save https://cdn.sheetjs.com/xlsx-0.18.7/xlsx-0.18.7.tgz # pnpm
$ yarn add     --save https://cdn.sheetjs.com/xlsx-0.18.7/xlsx-0.18.7.tgz # yarn

Once installed, the library can be imported under the name xlsx:

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:

// @deno-types="https://cdn.sheetjs.com/xlsx-0.18.7/package/types/index.d.ts"
import * as XLSX from 'https://cdn.sheetjs.com/xlsx-0.18.7/package/xlsx.mjs';

/* load the codepage support library for extended support with older formats  */
import * as cptable from 'https://cdn.sheetjs.com/xlsx-0.18.7/package/dist/cpexcel.full.mjs';
XLSX.set_cptable(cptable);

NodeJS

Tarballs are available on https://cdn.sheetjs.com.

Each individual version can be referenced using a similar URL pattern. https://cdn.sheetjs.com/xlsx-0.18.7/xlsx-0.18.7.tgz is the URL for 0.18.7

https://cdn.sheetjs.com/xlsx-latest/xlsx-latest.tgz is a link to the latest version and will refresh on each release.

Installation

Tarballs can be directly installed using a package manager:

$ npm  install https://cdn.sheetjs.com/xlsx-0.18.7/xlsx-0.18.7.tgz # npm
$ pnpm install https://cdn.sheetjs.com/xlsx-0.18.7/xlsx-0.18.7.tgz # pnpm
$ yarn add     https://cdn.sheetjs.com/xlsx-0.18.7/xlsx-0.18.7.tgz # yarn

For general stability, "vendoring" modules is the recommended approach:

1. Download the tarball (xlsx-0.18.7.tgz) for the desired version. The current version is available at https://cdn.sheetjs.com/xlsx-0.18.7/xlsx-0.18.7.tgz

2. Create a vendor subdirectory at the root of your project and move the tarball to that folder. Add it to your project repository.

3. Install the tarball using a package manager:

$ npm  install --save file:vendor/xlsx-0.18.7.tgz # npm
$ pnpm install --save file:vendor/xlsx-0.18.7.tgz # pnpm
$ yarn add            file:vendor/xlsx-0.18.7.tgz # yarn

The package will be installed and accessible as xlsx.

Usage

By default, the module supports require and it will automatically add support for streams and filesystem access:

var XLSX = require("xlsx");

The module also ships with xlsx.mjs for use with import. The mjs version does not automatically load native node modules:

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. https://cdn.sheetjs.com/xlsx-0.18.7/package/dist/xlsx.extendscript.js is the current version. After downloading the script, it can be directly referenced with a #include directive:

#include "xlsx.extendscript.js"
