Quick Overview
Officegen is a Node.js library that allows users to generate Microsoft Office documents programmatically. It supports the creation of PowerPoint presentations, Excel spreadsheets, and Word documents without requiring Microsoft Office to be installed on the system.
Pros
- Cross-platform compatibility, as it doesn't require Microsoft Office installation
- Supports multiple Office document types (PowerPoint, Excel, Word)
- Easy to use with a simple API
- Actively maintained with regular updates
Cons
- Limited formatting options compared to native Office applications
- May not support all advanced features of Office documents
- Performance can be slower for large or complex documents
- Documentation could be more comprehensive
Code Examples
Creating a PowerPoint presentation:
const officegen = require('officegen');
const fs = require('fs');
const pptx = officegen('pptx');
const slide = pptx.makeNewSlide();
slide.addText('Hello World!', { x: 100, y: 50, font_size: 56 });
const out = fs.createWriteStream('example.pptx');
pptx.generate(out);
Generating an Excel spreadsheet:
const officegen = require('officegen');
const fs = require('fs');
const xlsx = officegen('xlsx');
const sheet = xlsx.makeNewSheet();
sheet.name = 'My Sheet';
sheet.data[0] = ['Name', 'Age'];
sheet.data[1] = ['John Doe', 30];
sheet.data[2] = ['Jane Smith', 25];
const out = fs.createWriteStream('example.xlsx');
xlsx.generate(out);
Creating a Word document:
const officegen = require('officegen');
const fs = require('fs');
const docx = officegen('docx');
docx.createP().addText('Hello World!', { bold: true, underline: true });
const out = fs.createWriteStream('example.docx');
docx.generate(out);
Getting Started
To use Officegen in your Node.js project:
-
Install the package:
npm install officegen
-
Import the library in your JavaScript file:
const officegen = require('officegen');
-
Create a document of the desired type:
const pptx = officegen('pptx'); // or const xlsx = officegen('xlsx'); // or const docx = officegen('docx');
-
Add content to your document using the appropriate methods.
-
Generate the file:
const fs = require('fs'); const out = fs.createWriteStream('output.pptx'); pptx.generate(out);
Competitor Comparisons
A pure PHP library for reading and writing word processing documents
Pros of PHPWord
- Specifically designed for PHP, offering seamless integration with PHP projects
- Extensive documentation and active community support
- Supports a wider range of document formats, including OOXML, ODF, and RTF
Cons of PHPWord
- Limited to PHP environment, less versatile than officegen's Node.js platform
- May have a steeper learning curve for developers not familiar with PHP
- Performance can be slower for large document generation compared to officegen
Code Comparison
PHPWord:
$phpWord = new \PhpOffice\PhpWord\PhpWord();
$section = $phpWord->addSection();
$section->addText('Hello World!');
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007');
$objWriter->save('helloWorld.docx');
officegen:
let docx = officegen('docx');
let pObj = docx.createP();
pObj.addText('Hello World!');
docx.generate(fs.createWriteStream('helloWorld.docx'));
Both libraries offer straightforward methods to create simple documents. PHPWord's syntax is more verbose, reflecting its comprehensive feature set, while officegen provides a more concise approach. The choice between them often depends on the developer's preferred language and specific project requirements.
Open XML SDK by Microsoft
Pros of Open-XML-SDK
- More comprehensive support for Office Open XML formats
- Better performance for large document processing
- Stronger type safety and compile-time checks
Cons of Open-XML-SDK
- Steeper learning curve due to more complex API
- Limited to .NET environment
- Requires more code for simple operations
Code Comparison
officegen example:
var docx = officegen('docx');
var pObj = docx.createP();
pObj.addText('Simple text.');
Open-XML-SDK example:
using (WordprocessingDocument doc = WordprocessingDocument.Create(path, WordprocessingDocumentType.Document))
{
MainDocumentPart mainPart = doc.AddMainDocumentPart();
mainPart.Document = new Document(new Body(new Paragraph(new Run(new Text("Simple text.")))));
}
The officegen library offers a more straightforward API for simple document creation, while Open-XML-SDK provides more granular control over document structure at the cost of verbosity. Open-XML-SDK is better suited for complex document manipulation and processing large files efficiently, whereas officegen excels in quick, simple document generation across multiple platforms.
Easily generate and modify .docx files with JS/TS with a nice declarative API. Works for Node and on the Browser.
Pros of docx
- More focused on Word document generation, potentially offering more specialized features
- Active development with frequent updates and contributions
- Comprehensive documentation and examples available
Cons of docx
- Limited to Word documents, while officegen supports multiple Office formats
- May have a steeper learning curve for users familiar with officegen's API
- Potentially less flexible for generating other Office file types
Code Comparison
officegen:
var officegen = require('officegen');
var docx = officegen('docx');
var pObj = docx.createP();
pObj.addText('Hello World!');
docx:
import { Document, Paragraph, TextRun } from "docx";
const doc = new Document();
const paragraph = new Paragraph({
children: [new TextRun("Hello World!")]
});
doc.addParagraph(paragraph);
Both libraries allow for creating Word documents with simple text content. officegen uses a more straightforward API, while docx offers a more object-oriented approach. The choice between them may depend on the specific project requirements, desired features, and the developer's familiarity with each library's syntax and structure.

Installation:
$ npm install officegen
Microsoft PowerPoint basic usage example:
const officegen = require('officegen')
const fs = require('fs')
// Create an empty PowerPoint object:
let pptx = officegen('pptx')
// Let's add a title slide:
let slide = pptx.makeTitleSlide('Officegen', 'Example to a PowerPoint document')
// Pie chart slide example:
slide = pptx.makeNewSlide()
slide.name = 'Pie Chart slide'
slide.back = 'ffff00'
slide.addChart(
{
title: 'My production',
renderType: 'pie',
data:
[
{
name: 'Oil',
labels: ['Czech Republic', 'Ireland', 'Germany', 'Australia', 'Austria', 'UK', 'Belgium'],
values: [301, 201, 165, 139, 128, 99, 60],
colors: ['ff0000', '00ff00', '0000ff', 'ffff00', 'ff00ff', '00ffff', '000000']
}
]
}
)
// Let's generate the PowerPoint document into a file:
return new Promise((resolve, reject) => {
let out = fs.createWriteStream('example.pptx')
// This one catch only the officegen errors:
pptx.on('error', function(err) {
reject(err)
})
// Catch fs errors:
out.on('error', function(err) {
reject(err)
})
// End event after creating the PowerPoint file:
out.on('close', function() {
resolve()
})
// This async method is working like a pipe - it'll generate the pptx data and put it into the output stream:
pptx.generate(out)
})
Since that officegen is using node.js events you can also create a document directly into a http respons stream:
const officegen = require('officegen')
const http = require('http')
/**
* This is a simple web server that response with a PowerPoint document.
*/
http.createServer(function(req, res) {
// We'll send a generated on the fly PowerPoint document without using files:
if (req.url == '/') {
// Create an empty PowerPoint object:
let pptx = officegen('pptx')
// Let's create a new slide:
var slide = pptx.makeNewSlide()
slide.name = 'Hello World'
// Change the background color:
slide.back = '000000'
// Declare the default color to use on this slide:
slide.color = 'ffffff'
// Basic way to add text string:
slide.addText('Created on the fly using a http server!')
//
// Let's generate the PowerPoint document directly into the response stream:
//
response.writeHead(200, {
'Content-Type':
'application/vnd.openxmlformats-officedocument.presentationml.presentation',
'Content-disposition': 'attachment filename=out.pptx'
})
// Content types related to Office documents:
// .xlsx application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
// .xltx application/vnd.openxmlformats-officedocument.spreadsheetml.template
// .potx application/vnd.openxmlformats-officedocument.presentationml.template
// .ppsx application/vnd.openxmlformats-officedocument.presentationml.slideshow
// .pptx application/vnd.openxmlformats-officedocument.presentationml.presentation
// .sldx application/vnd.openxmlformats-officedocument.presentationml.slide
// .docx application/vnd.openxmlformats-officedocument.wordprocessingml.document
// .dotx application/vnd.openxmlformats-officedocument.wordprocessingml.template
// .xlam application/vnd.ms-excel.addin.macroEnabled.12
// .xlsb application/vnd.ms-excel.sheet.binary.macroEnabled.12
// This one catch only the officegen errors:
pptx.on('error', function(err) {
res.end(err)
})
// Catch response errors:
res.on('error', function(err) {
res.end(err)
})
// End event after sending the PowerPoint data:
res.on('finish', function() {
res.end()
})
// This async method is working like a pipe - it'll generate the pptx data and pass it directly into the output stream:
pptx.generate(res)
} else {
res.end('Invalid Request!')
} // Endif.
}).listen(3000)
