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)

Microsoft Word basic usage example:

const officegen = require('officegen')
const fs = require('fs')

// Create an empty Word object:
let docx = officegen('docx')

// Officegen calling this function after finishing to generate the docx document:
docx.on('finalize', function(written) {
  console.log(
    'Finish to create a Microsoft Word document.'
  )
})

// Officegen calling this function to report errors:
docx.on('error', function(err) {
  console.log(err)
})

// Create a new paragraph:
let pObj = docx.createP()

pObj.addText('Simple')
pObj.addText(' with color', { color: '000088' })
pObj.addText(' and back color.', { color: '00ffff', back: '000088' })

pObj = docx.createP()

pObj.addText('Since ')
pObj.addText('officegen 0.2.12', {
  back: '00ffff',
  shdType: 'pct12',
  shdColor: 'ff0000'
}) // Use pattern in the background.
pObj.addText(' you can do ')
pObj.addText('more cool ', { highlight: true }) // Highlight!
pObj.addText('stuff!', { highlight: 'darkGreen' }) // Different highlight color.

pObj = docx.createP()

pObj.addText('Even add ')
pObj.addText('external link', { link: 'https://github.com' })
pObj.addText('!')

pObj = docx.createP()

pObj.addText('Bold + underline', { bold: true, underline: true })

pObj = docx.createP({ align: 'center' })

pObj.addText('Center this text', {
  border: 'dotted',
  borderSize: 12,
  borderColor: '88CCFF'
})

pObj = docx.createP()
pObj.options.align = 'right'

pObj.addText('Align this text to the right.')

pObj = docx.createP()

pObj.addText('Those two lines are in the same paragraph,')
pObj.addLineBreak()
pObj.addText('but they are separated by a line break.')

docx.putPageBreak()

pObj = docx.createP()

pObj.addText('Fonts face only.', { font_face: 'Arial' })
pObj.addText(' Fonts face and size.', { font_face: 'Arial', font_size: 40 })

docx.putPageBreak()

pObj = docx.createP()

// We can even add images:
pObj.addImage('some-image.png')

// Let's generate the Word document into a file:

let out = fs.createWriteStream('example.docx')

out.on('error', function(err) {
  console.log(err)
})

// Async call to generate the output file:
docx.generate(out)

Microsoft Excel basic usage example:

const officegen = require('officegen')
const fs = require('fs')

// Create an empty Excel object:
let xlsx = officegen('xlsx')

// Officegen calling this function after finishing to generate the xlsx document:
xlsx.on('finalize', function(written) {
  console.log(
    'Finish to create a Microsoft Excel document.'
  )
})

// Officegen calling this function to report errors:
xlsx.on('error', function(err) {
  console.log(err)
})

let sheet = xlsx.makeNewSheet()
sheet.name = 'Officegen Excel'

// Add data using setCell:

sheet.setCell('E7', 42)
sheet.setCell('I1', -3)
sheet.setCell('I2', 3.141592653589)
sheet.setCell('G102', 'Hello World!')

// The direct option - two-dimensional array:

sheet.data[0] = []
sheet.data[0][0] = 1
sheet.data[1] = []
sheet.data[1][3] = 'some'
sheet.data[1][4] = 'data'
sheet.data[1][5] = 'goes'
sheet.data[1][6] = 'here'
sheet.data[2] = []
sheet.data[2][5] = 'more text'
sheet.data[2][6] = 900
sheet.data[6] = []
sheet.data[6][2] = 1972

// Let's generate the Excel document into a file:

let out = fs.createWriteStream('example.xlsx')

out.on('error', function(err) {
  console.log(err)
})

// Async call to generate the output file:
xlsx.generate(out)
