Node XLSX

Excel file parser/builder that relies on js-xlsx.

Usage

Examples

1. Parsing a xlsx from file/buffer, outputs an array of worksheets

import xlsx from 'node-xlsx';
// Or var xlsx = require('node-xlsx').default;

// Parse a buffer
const workSheetsFromBuffer = xlsx.parse(fs.readFileSync(`${__dirname}/myFile.xlsx`));
// Parse a file
const workSheetsFromFile = xlsx.parse(`${__dirname}/myFile.xlsx`);

2. Building a xlsx

import xlsx from 'node-xlsx';
// Or var xlsx = require('node-xlsx').default;

const data = [[1, 2, 3], [true, false, null, 'sheetjs'], ['foo', 'bar', new Date('2014-02-19T14:30Z'), '0.3'], ['baz', null, 'qux']];
var buffer = xlsx.build([{name: "mySheetName", data: data}]); // Returns a buffer

• Building a xlsx (spannig multiple rows A1:A4)

import xlsx from 'node-xlsx';
// Or var xlsx = require('node-xlsx').default;

const data = [[1, 2, 3], [true, false, null, 'sheetjs'], ['foo', 'bar', new Date('2014-02-19T14:30Z'), '0.3'], ['baz', null, 'qux']];
const range = {s: {c: 0, r:0 }, e: {c:0, r:3}}; // A1:A4
const option = {'!merges': [ range ]};

var buffer = xlsx.build([{name: "mySheetName", data: data}], option); // Returns a buffer

Troubleshooting

This library requires at lease nodeJS v4. For legacy versions, you can use this workaround before using the lib.

npm i --save object-assign
Object.prototype.assign = require('object-assign');
