$ npm install Ziv-Barber/officegen#master

This module is depending on:

• archiver
• setimmediate
• fast-image-size
• xmlbuilder
• lodash

Public API:

Creating the document object:

var officegen = require('officegen');

There are two ways to use the officegen returned function to create the document object:

var myDoc = officegen ( '' );

var myDoc = officegen ({
  'type': ''
  // More options here (if needed)
});

Generating PowerPoint 2007 object:

var pptx = officegen ( 'pptx' );

Generating Word 2007 object:

var docx = officegen ( 'docx' );

Generating Excel 2007 object:

var xlsx = officegen ( 'xlsx' );

General events of officegen:

• 'finalize' - been called after finishing to create the document.
• 'error' - been called on error.

Event examples:

pptx.on ( 'finalize', function ( written ) {
      console.log ( 'Finish to create a PowerPoint file.\nTotal bytes created: ' + written + '\n' );
    });

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

Another way to register either 'finalize' or 'error' events:

var pptx = officegen ({
    'type': 'pptx', // or 'xlsx', etc
    'onend': function ( written ) {
        console.log ( 'Finish to create a PowerPoint file.\nTotal bytes created: ' + written + '\n' );
    },
    'onerr': function ( err ) {
        console.log ( err );
    }
});

If you are preferring to use callbacks instead of events you can pass your callbacks to the generate method (see below).

Now you should fill the object with data (we'll see below) and then you should call generate with an output stream to create the output Office document.

Example with pptx:

var out = fs.createWriteStream ( 'out.pptx' );

pptx.generate ( out );
out.on ( 'close', function () {
  console.log ( 'Finished to create the PPTX file!' );
});

Passing callbacks to generate:

var out = fs.createWriteStream ( 'out.pptx' );

pptx.generate ( out, {
  'finalize': function ( written ) {
    console.log ( 'Finish to create a PowerPoint file.\nTotal bytes created: ' + written + '\n' );
  },
  'error': function ( err ) {
    console.log ( err );
  }
});

Generating HTTP stream (no file been created):

var http = require("http");
var officegen = require('officegen');

http.createServer ( function ( request, response ) {
  response.writeHead ( 200, {
    "Content-Type": "application/vnd.openxmlformats-officedocument.presentationml.presentation",
    'Content-disposition': 'attachment; filename=surprise.pptx'
    });

  var pptx = officegen ( 'pptx' );

  pptx.on ( 'finalize', function ( written ) {
      // ...
      });

  pptx.on ( 'error', function ( err ) {
      // ...
      });

  // ... (fill pptx with data)

  pptx.generate ( response );
}).listen ( 3000 );

Put data inside the document object:

MS-Office document properties (for all document types):

The default Author of all the documents been created by officegen is 'officegen'. If you want to put anything else please use the 'creator' option when calling the officegen function:

var pptx = officegen ({
    'type': 'pptx', // or 'xlsx', etc
	'creator': ''
});

Change the document title (pptx,ppsx,docx):

var pptx = officegen ({
    'type': 'pptx',
	'title': '<title>'
});

// or

pptx.setDocTitle ( '&lt;title&gt;' );

For Word only:

var docx = officegen ({
    'type': 'docx',
	'subject': '...',
	'keywords': '...',
	'description': '...'
});

// or

docx.setDocSubject ( '...' );
docx.setDocKeywords ( '...' );
docx.setDescription ( '...' );

PowerPoint:

Setting slide size:

pptx.setSlideSize ( cx, cy, type )

Arguments:

• cx - width of the slide (in pixels)
• cy - height of the slide (in pixels)
• Supported types:
  • '35mm'
  • 'A3'
  • 'A4'
  • 'B4ISO'
  • 'B4JIS'
  • 'B5ISO'
  • 'B5JIS'
  • 'banner'
  • 'custom'
  • 'hagakiCard'
  • 'ledger'
  • 'letter'
  • 'overhead'
  • 'screen16x10'
  • 'screen16x9'
  • 'screen4x3'

Creating a new slide:

slide = pptx.makeNewSlide ();

For creating a new slide using a layout:

slide = pptx.makeNewSlide ({
	userLayout: 'title'
});
slide.setTitle ( 'The title' );
slide.setSubTitle ( 'Another text' ); // For either 'title' and 'secHead' only.
// for 'obj' layout use slide.setObjData ( ... ) to change the object element inside the slide.

userLayout can be:

• 'title': the first layout of Office (title).
• 'obj': the 2nd layout of Office (with one title and one object).
• 'secHead': the 3rd layout of Office.

Or more advance example:

slide = pptx.makeNewSlide ({
	userLayout: 'title'
});
// Both setTitle and setSubTitle excepting all the parameters that you can pass to slide.addText - see below:
slide.setTitle ([
	// This array is like a paragraph and you can use any settings that you pass for creating a paragraph,
	// Each object here is like a call to addText:
	{ text: 'Hello ', options: { font_size: 56 } },
	{ text: 'World!', options: { font_size: 56, font_face: 'Arial', color: 'ffff00' } }
]);

The returned object from makeNewSlide representing a single slide. Use it to add objects into this slide. You must create at last one slide on your pptx/ppsx document.

Inside each slide you can place objects, for example: text box, shapes, images, etc.

Properties of the slide object itself:

• "name" - name for this slide.
• "back" - the background color.
• "color" - the default font color to use.
• "show" - change this property to false if you want to disable this slide.

The slide object supporting the following methods:

• addText ( text, options )
• addShape ( shape, options )
• addImage ( image, options )
• addChart ( chartInfo )
• addTable ( rowsSpec, options )

Read only methods:

• getPageNumber - return the ID of this slide.

Common properties that can be added to the options object for all the add based methods:

• x - start horizontal position. Can be either number, percentage or 'c' to center this object (horizontal).
• y - start vertical position. Can be either number, percentage or 'c' to center this object (vertical).
• cx - the horizontal size of this object. Can be either number or percentage of the total horizontal size.
• cy - the vertical size of this object. Can be either number or percentage of the total vertical size.
• color - the font color for text.
• fill - the background color.
• line - border color / line color.
• flip_vertical: true - flip the object vertical.
• flip_horizontal: true - flip the object horizontal
• shape - see below.

Font properties:

• font_face
• font_size (in points)
• bold: true
• underline: true
• char_spacing: floating point number (kerning)
• baseline: percent (of font size). Used for superscript and subscript.

Text alignment properties:

• align - can be either 'left' (default), 'right', 'center' or 'justify'.
• indentLevel - indent level (number: 0+, default = 0).

Line/border extra properties (only effecting if the 'line' property exist):

• 'line_size' - line width in pixels.
• 'line_head' - the shape name of the line's head side (either: 'triangle', 'stealth', etc).
• 'line_tail' - the shape name of the line's tail side (either: 'triangle', 'stealth', etc).

The 'shape' property:

Normally every object is a rectangle but you can change that for every object using the shape property, or in case that you don't need to write any text inside that object, you can use the addShape method instead of addText. Use the shape property only if you want to use a shape other then the default and you also want to add text inside it.

Shapes list:

• 'rect' (default) - rectangle.
• 'ellipse'
• 'roundRect' - round rectangle.
• 'triangle'
• 'line' - draw line.
• 'cloud'
• 'hexagon'
• 'flowChartInputOutput'
• 'wedgeEllipseCallout'
• (much more shapes already supported - I'll update this list later)

Please note that every color property can be either:

• String of the color code. For example: 'ffffff', '000000', '888800', etc.
• Color object:
  • 'type' - The type of the color fill to use. Right now only 'solid' and 'gradient' supported.
  • 'color' - String with the color code to use.
  • 'alpha' - transparent level (0-100).
• For 'gradient' fill:
  • 'color' - Array of strings with the color code to use OR array of object, each object include "color" and "position" parameters. i.e. [{"position": 0, "color": '000000'}, {}, ...]
  • 'alpha' - transparent level (0-100).
  • 'angle' - (optional) the angle of gradient rotation

Adding images:

Just pass the image file name as the first parameter to addImage and the 2nd parameter, which is optional, is normal options objects and you can use all the common properties ('cx', 'cy', 'y', 'x', etc).

Examples:

Changing the background color of a slide:

slide.back = '000088';

or:

slide.back = { type: 'solid', color: '008800' };

Examples how to put text inside the new slide:

// Change the background color:
slide.back = '000000';

// Declare the default color to use on this slide (default is black):
slide.color = 'ffffff';

// Basic way to add text string:
slide.addText ( 'This is a test' );
slide.addText ( 'Fast position', 0, 20 );
slide.addText ( 'Full line', 0, 40, '100%', 20 );

// Add text box with multi colors and fonts:
slide.addText ( [
  { text: 'Hello ', options: { font_size: 56 } },
  { text: 'World!', options: { font_size: 56, font_face: 'Arial', color: 'ffff00' } }
  ], { cx: '75%', cy: 66, y: 150 } );
// Please note that you can pass object as the text parameter to addText.

slide.addText ( 'Office generator', {
  y: 66, x: 'c', cx: '50%', cy: 60, font_size: 48,
  color: '0000ff' } );

slide.addText ( 'Big Red', {
  y: 250, x: 10, cx: '70%',
  font_face: 'Wide Latin', font_size: 54,
  color: 'cc0000', bold: true, underline: true } );

Speaker notes:

PowerPoint slides can contain speaker notes, to do that use the setSpeakerNote method:

slide.setSpeakerNote ( 'This is a speaker note!' );

Charts:

PowerPoint slides can contain charts with embedded data. To create a chart:

slide.addChart( chartInfo)

Where chartInfo object is an object that takes the following attributes:

• data - an array of data, see examples below
• renderType - specifies base chart type, may be one of "bar", "pie", "group-bar", "column", "stacked-column", "line"
• title - chart title (default: none)
• valAxisTitle - value axis title (default: none)
• catAxisTitle - category axis title (default: none)
• valAxisMinValue - value axis min (default: none)
• valAxisMaxValue - vlaue axis max value (default: none)
• valAxisNumFmt - value axis format, e.g "$0" or "0%" (default: none)
• valAxisMajorGridlines - true|false (false)
• valAxisMinorGridlines - true|false (false)
• valAxisCrossAtMaxCategory - true|false (false)
• catAxisReverseOrder - true|false (false)
• fontSize - text size for chart, e.g. "1200" for 12pt type
• xml - optional XML overrides to <c:chart> as a Javascript object that is mixed in

Also, the overall chart and each data series take an an optional xml attribute, which specifies XML overrides to the <c:series> attribute.

• The xml argument for the chartInfo is mixed in to the c:chartSpace attribute.
• The xml argument for the data series is mixed into the c:ser attribute.

For instance, to specify the overall text size, you can specify the following on the chartInfo object. The snippet below is what happens under the scenes when you specify fontSize: 1200

chartInfo = {
 // ....
 "xml": {
      "c:txPr": {
        "a:bodyPr": {},
        "a:listStyle": {},
        "a:p": {
          "a:pPr": {
            "a:defRPr": {
              "@sz": "1200"
            }
          },
          "a:endParaRPr": {
            "@lang": "en-US"
          }
        }
      }
    }

Tables:

Add a table to a PowerPoint slide:

 var rows = [];
  for (var i = 0; i < 12; i++) {
    var row = [];
    for (var j = 0; j < 5; j++) {
      row.push("[" + i + "," + j + "]");
    }
    rows.push(row);
  }
  slide.addTable(rows, {});

Specific options for tables (in addition to standard : x, y, cx, cy, etc.) :

• columnWidth : width of all columns (same size for all columns). Must be a number (~1 000 000)
• columnWidths : list of width for each columns (custom size per column). Must be array of number. This param will overwrite columnWidth if both are given

Formatting can also be applied directly to a cell:

var rows = [];
rows.push([
	{
		val: "Category",
        	opts: {
          		font_face   : "Arial",
          		align       : "l",
          		bold        : 0
        	}
      },
      {
        	val  :"Average Score",
        	opts: {
          		font_face   : "Arial",
          		align       : "r",
          		bold        : 1,
          		font_color  : "000000",
          		fill_color  : "f5f5f5"
        	}
      }
]);
slide.addTable(rows, {});

Word:

All the text data in Word is saved in paragraphs. To add a new paragraph:

var pObj = docx.createP ();

Paragraph options:

pObj.options.align = 'center'; // Also 'right' or 'justify'.
pObj.options.indentLeft = 1440; // Indent left 1 inch

Every list item is also a paragraph so:

var pObj = docx.createListOfDots ();

var pObj = docx.createListOfNumbers ();

Now you can fill the paragraph object with one or more text strings using the addText method:

pObj.addText ( 'Simple' );

pObj.addText ( ' with color', { color: '000088' } );

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

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

pObj.addText ( 'Fonts face only.', { font_face: 'Arial' } );

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

pObj.addText ( 'External link', { link: 'https://github.com' } );

// Hyperlinks to bookmarks also supported:
pObj.addText ( 'Internal link', { hyperlink: 'myBookmark' } );
// ...
// Start somewhere a bookmark:
pObj.startBookmark ( 'myBookmark' );
// ...
// You MUST close your bookmark:
pObj.endBookmark ();

Add an image to a paragraph:

var path = require('path');

pObj.addImage ( path.resolve(__dirname, 'myFile.png' ) ); pObj.addImage ( path.resolve(__dirname, 'myFile.png', { cx: 300, cy: 200 } ) );

To add a line break;

var pObj = docx.createP ();
pObj.addLineBreak ();

To add a page break:

docx.putPageBreak ();

To add a horizontal line:

var pObj = docx.createP ();
pObj.addHorizontalLine ();

To add a back line:

var pObj = docx.createP ({ backline: 'E0E0E0' });
pObj.addText ( 'Backline text1' );
pObj.addText ( ' text2' );

To add a table:

var table = [
  [{
    val: "No.",
    opts: {
      cellColWidth: 4261,
      b:true,
      sz: '48',
      shd: {
        fill: "7F7F7F",
        themeFill: "text1",
        "themeFillTint": "80"
      },
      fontFamily: "Avenir Book"
    }
  },{
    val: "Title1",
    opts: {
      b:true,
      color: "A00000",
      align: "right",
      shd: {
        fill: "92CDDC",
        themeFill: "text1",
        "themeFillTint": "80"
      }
    }
  },{
    val: "Title2",
    opts: {
      align: "center",
      vAlign: "center",
      cellColWidth: 42,
      b:true,
      sz: '48',
      shd: {
        fill: "92CDDC",
        themeFill: "text1",
        "themeFillTint": "80"
      }
    }
  }],

  tableSize: 24,
  tableColor: "ada",
  tableAlign: "left",
  tableFontFamily: "Comic Sans MS",

}

docx.createTable (table, tableStyle);

Header and footer:

// Add a header:
var header = docx.getHeader ().createP ();
header.addText ( 'This is the header' );
// Please note that the object header here is a paragraph object so you can use ANY of the paragraph API methods also for header and footer.
// The getHeader () method excepting a string parameter:
// getHeader ( 'even' ) - change the header for even pages.
// getHeader ( 'first' ) - change the header for the first page only.

Excel:

sheet = xlsx.makeNewSheet ();
sheet.name = 'My Excel Data';

Fill cells:

// Using setCell:
sheet.setCell ( 'E7', 340 );
sheet.setCell ( 'G102', 'Hello World!' );

// Direct way:
sheet.data[0] = [];
sheet.data[0][0] = 1;
sheet.data[0][1] = 2;
sheet.data[1] = [];
sheet.data[1][3] = 'abc';
