Frameworks and Bundlers

Each standalone release package is available at https://cdn.sheetjs.com/. The NodeJS package is designed to be used with frameworks and bundlers. It is a proper ECMAScript Module release which can be optimized with developer tools.

https://cdn.sheetjs.com/xlsx-{current}/xlsx-{current}.tgz is the URL for version {current}

Installation

Tarballs can be directly installed using a package manager:

{`\ npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} {`\ pnpm install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} {`\ yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}

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

import { read, writeFileXLSX } from "xlsx";

The "Bundlers" demo includes examples for specific tools.

:::tip pass

Watch the repo or subscribe to the RSS feed to be notified when new versions are released!

:::

:::warning

Older releases are technically available on the public npm registry as xlsx, but the registry is out of date. The latest version on that registry is 0.18.5

This is a known registry bug

https://cdn.sheetjs.com/ is the authoritative source for SheetJS scripts.

For existing projects, the easiest approach is to uninstall and reinstall:

{`\ npm rm --save xlsx npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} {`\ pnpm rm xlsx pnpm install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} {`\ yarn remove xlsx yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}

When the xlsx library is a dependency of a dependency, the overrides field in package.json can control module resolution:

{\ { // highlight-start "overrides": { "xlsx": "https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz" } // highlight-end }}

Vendoring

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

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

2. Create a vendor subfolder 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 i --save file:vendor/xlsx-${current}.tgz`} {`\ pnpm install file:vendor/xlsx-${current}.tgz`} {`\ yarn add file:vendor/xlsx-${current}.tgz`}

The package will be installed and accessible as xlsx.

Usage

With most frameworks and bundler tools, named imports are recommended:

import { read, utils } from 'xlsx';

Some legacy bundlers require the glob import:

import * as XLSX from 'xlsx';
const { read, utils } = XLSX;

For legacy bundlers that support CommonJS, require will work:

var XLSX = require("xlsx");
var read = XLSX.read, utils = XLSX.utils;

The "Bundlers" demo includes examples for specific tools.

Encoding support

If Encoding support is required, cpexcel.full.mjs must be manually imported:

/* 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);
