React

The xlsx.core.min.js and xlsx.full.min.js scripts are designed to be dropped into web pages with script tags e.g.

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

The library can also be imported directly from JSX code with:

import * as XLSX from 'xlsx';

This demo shows a simple JSX component transpiled in the browser using the babel standalone library. Since there is no standard React table model, this demo settles on the array of arrays approach.

Other scripts in this demo show:

  • server-rendered React component (with next.js)
  • preact using the react compatibility library
  • react-native deployment for iOS and android

Internal State

The simplest state representation is an array of arrays. To avoid having the table component depend on the library, the column labels are precomputed. The state in this demo is shaped like the following object:

{
  cols: [
    { name: "A", key: 0 },
    { name: "B", key: 1 },
    { name: "C", key: 2 },
  ],
  data: [
    [ "id",    "name", "value" ],
    [    1, "sheetjs",    7262 ]
    [    2, "js-xlsx",    6969 ]
  ]
}

The appropriate state model is application-specific.

React Native

Reproducing the full project is straightforward:

react-native init SheetJS
cd SheetJS
npm i -S xlsx react react-native react-native-table-component react-native-fs
cp ../react-native.js index.ios.js
cp ../react-native.js index.android.js
react-native link

This uses react-native-fs to read and write files on devices. The app will prompt before reading and after writing data. The printed location will be:

  • android: path in the device filesystem
  • iOS simulator: local path to file
  • iOS device: a path accessible from iTunes App Documents view
