Use JavaScript to Create a PowerPoint presentation with your web browser right now: https://gitbrent.github.io/PptxGenJS
<script lang="javascript" src="PptxGenJS/libs/jquery.min.js"></script>
<script lang="javascript" src="PptxGenJS/libs/jszip.min.js"></script>
<script lang="javascript" src="PptxGenJS/dist/pptxgen.js"></script>
<script lang="javascript" src="PptxGenJS/dist/pptxgen.bundle.js"></script>
bower install pptxgen
npm install pptxgenjs
var pptx = require("pptxgenjs");
PptxGenJS PowerPoint presentations are created via JavaScript by following 4 basic steps:
- Create a new Presentation
- Add a Slide
- Add one or more objects (Tables, Shapes, Images, Text and Media) to the Slide
- Save the Presentation
var pptx = new PptxGenJS();
var slide = pptx.addNewSlide();
slide.addText('Hello World!', { x:1.5, y:1.5, font_size:18, color:'363636' });
pptx.save('Sample Presentation');
That's really all there is to it!
A Presentation is a single .pptx
file. When creating more than one Presentation, declare the pptx again to
start with a new, empty Presentation.
Client Browser:
var pptx = new PptxGenJS();
Node.js:
var pptx = require("pptxgenjs");
There are several optional properties that can be set:
pptx.setAuthor('Brent Ely');
pptx.setCompany('S.T.A.R. Laboratories');
pptx.setRevision('15');
pptx.setSubject('Annual Report');
pptx.setTitle('PptxGenJS Sample Presentation');
Setting the Layout (applies to all Slides in the Presentation):
pptx.setLayout('LAYOUT_WIDE');
Layout Name | Default | Layout Slide Size |
---|---|---|
LAYOUT_16x9 |
Yes | 10 x 5.625 inches |
LAYOUT_16x10 |
No | 10 x 6.25 inches |
LAYOUT_4x3 |
No | 10 x 7.5 inches |
LAYOUT_WIDE |
No | 13.3 x 7.5 inches |
LAYOUT_USER |
No | user defined - see below (inches) |
Custom user defined Layout sizes are supported - just supply a name
and the size in inches.
- Defining a new Layout using an object will also set this new size as the current Presentation Layout
// Defines and sets this new layout for the Presentation
pptx.setLayout({ name:'A3', width:16.5, height:11.7 });
Right-to-Left (RTL) text is supported. Simply set the RTL mode at the Presentation-level.
pptx.setRTL(true);
Syntax:
var slide = pptx.addNewSlide();
slide.bkgd = 'F1F1F1';
slide.color = '696969';
Option | Type | Unit | Default | Description | Possible Values |
---|---|---|---|---|---|
bkgd |
string | FFFFFF |
background color | hex color code or scheme color constant. | |
color |
string | 000000 |
default text color | hex color code or scheme color constant. |
// Create a new Slide that will inherit properties from a pre-defined master page (margins, logos, text, background, etc.)
var slide1 = pptx.addNewSlide( pptx.masters.TITLE_SLIDE );
// The background color can be overridden on a per-slide basis:
var slide2 = pptx.addNewSlide( pptx.masters.TITLE_SLIDE, {bkgd:'FFFCCC'} );
slide.slideNumber({ x:1.0, y:'90%' });
// Slide Numbers can be styled:
slide.slideNumber({ x:1.0, y:'90%', fontFace:'Courier', fontSize:32, color:'CF0101' });
Option | Type | Unit | Default | Description | Possible Values |
---|---|---|---|---|---|
x |
number | inches | 0.3 |
horizontal location | 0-n OR 'n%'. (Ex: {x:'10%'} places number 10% from left edge) |
y |
number | inches | 90% |
vertical location | 0-n OR 'n%'. (Ex: {y:'90%'} places number 90% down the Slide) |
color |
string | text color | hex color code or scheme color constant. Ex: {color:'0088CC'} |
||
fontFace |
string | font face | any available font. Ex: {fontFace:Arial} |
||
fontSize |
number | points | font size | 8-256. Ex: {fontSize:12} |
The Slide object returns a reference to itself, so calls can be chained.
Example:
slide
.addImage({ path:'images/logo1.png', x:1, y:2, w:3, h:3 })
.addImage({ path:'images/logo2.jpg', x:5, y:3, w:3, h:3 })
.addImage({ path:'images/logo3.png', x:9, y:4, w:3, h:3 });
Presentations require nothing more than passing a filename to save()
. Node.js users have more options available
examples of which can be found below.
- Simply provide a filename
pptx.save('Demo-Media');
- Node can accept a callback function that will return the filename once the save is complete
- Node can also be used to stream a powerpoint file - simply pass a filename that begins with "http"
- Output type can be specified by passing an optional JSZip output type
// Example A: File will be saved to the local working directory (`__dirname`)
pptx.save('Node_Demo');
// Example B: Inline callback function
pptx.save('Node_Demo', function(filename){ console.log('Created: '+filename); });
// Example C: Predefined callback function
pptx.save('Node_Demo', saveCallback);
// Example D: Use a filename of "http" or "https" to receive the powerpoint binary data in your callback
// (Used for streaming the presentation file via http. See the `nodejs-demo.js` file for a working example.)
pptx.save('http', streamCallback);
// Example E: Save using various JSZip output types: ['arraybuffer', 'base64', 'binarystring', 'blob', 'nodebuffer', 'uint8array']
pptx.save('jszip', saveCallback, 'base64');
Client-Side:
- In order to generate a new, unique Presentation just create a new instance of the library then add objects and save as normal.
var pptx = require("pptxgenjs");
pptx.addNewSlide().addText('Presentation 1', {x:1, y:1});
pptx.save('PptxGenJS-Presentation-1');
// Create a new instance ("Reset")
pptx = require("pptxgenjs");
pptx.addNewSlide().addText('Presentation 2', {x:1, y:1});
pptx.save('PptxGenJS-Presentation-2');
Node.js:
- Multiple presentations are a bit more complicated in Node - see Issue #83
Objects on the Slide are ordered from back-to-front based upon the order they were added.
For example, if you add an Image, then a Shape, then a Textbox: the Textbox will be in front of the Shape, which is in front of the Image.
// Syntax
slide.addChart({TYPE}, {DATA}, {OPTIONS});
- Chart type can be any one of
pptx.charts
- Currently:
pptx.charts.AREA
,pptx.charts.BAR
,pptx.charts.LINE
,pptx.charts.PIE
,pptx.charts.DOUGHNUT
- Chart types can be any one of
pptx.charts
, althoughpptx.charts.AREA
,pptx.charts.BAR
, andpptx.charts.LINE
will give the best results. - There should be at least two chart-types. There should always be two value axes and category axes.
- Multi Charts have a different function signature than standard. There are two parameters:
chartTypes
: Array of objects, each withtype
,data
, andoptions
objects.options
: Standard options as used with single charts. Can include axes options.- Columns makes the most sense in general. Line charts cannot be rotated to match up with horizontal bars (a PowerPoint limitation).
- Can optionally have a secondary value axis.
- If there is secondary value axis, a secondary category axis is required in order to render, but currently always uses the primary labels. It is recommended to use
catAxisHidden: true
on the secondary category axis. - Standard options are used, and the chart-type-options are mixed in to each.

Tables will auto-page by default and the table on new Slides will use the current Slide's top margin
value as the starting point for y
.
Tables will retain their existing x
, w
, and colW
values as they are continued onto subsequent Slides.
autoPage
: allows the auto-paging functionality (as table rows overflow the Slide, new Slides will be added) to be disabled.lineWeight
: adjusts the calculated height of lines. If too much empty space is left under each table, then increase lineWeight value. Conversely, if the tables are overflowing the bottom of the Slides, then reduce the lineWeight value. Also helpful when using some fonts that do not have the usual golden ratio.newPageStartY
: provides the ability to specify where new tables will be placed on new Slides. For example, you may place a table halfway down a Slide, but you wouldn't that to be the starting location for subsequent tables. Use this option to ensure there is no wasted space and to guarantee a professional look.

- Formatting Options passed to
slide.addTable()
apply to every cell in the table - You can selectively override formatting at a cell-level providing any Formatting Option in the cell
options
- Table cells can be either a plain text string or an object with text and options properties
- When using an object, any of the formatting options above can be passed in
options
and will apply to that cell only - Cell borders can be removed (aka: borderless table) by passing a 'none' (Ex:
border:'none'
)
Bullets and word-level formatting are supported inside table cells. Passing an array of objects with text/options values
as the text
value allows fine-grained control over the text inside cells.
- Available formatting options are here: Text Options

NOTES
- SVG images are not currently supported in PowerPoint or PowerPoint Online (even when encoded into base64). PptxGenJS does properly encode and include SVG images, so they will begin showing once Microsoft adds support for this image type.
- Using
path
to add remote images (images from a different server) is not currently supported.
Deprecation Warning
Old positional parameters (e.g.: slide.addImage('images/chart.png', 1, 1, 6, 3)
) are now deprecated as of 1.1.0

// Image by data (base64-encoding)
slide.addImage({ data:'image/png;base64,iVtDafDrBF[...]=', x:3.0, y:5.0, w:6.0, h:3.0 });
// NOTE: Slide API calls return the same slide, so you can chain calls:
slide.addImage({ path:'images/cc_license_comp_chart.png', x:6.6, y:0.75, w:6.30, h:3.70 })

The sizing
option provides cropping and scaling an image to a specified area. The property expects an object with the following structure:
Property | Type | Unit | Default | Description | Possible Values |
---|---|---|---|---|---|
type |
string | sizing algorithm | 'crop' , 'contain' or 'cover' |
||
w |
number | inches | w of the image |
area width | 0-n |
h |
number | inches | h of the image |
area height | 0-n |
x |
number | inches | 0 |
area horizontal position related to the image | 0-n (effective for crop only) |
y |
number | inches | 0 |
area vertical position related to the image | 0-n (effective for crop only) |
Particular type
values behave as follows:
contain
works as CSS propertybackground-size
— shrinks the image (ratio preserved) to the area given byw
andh
so that the image is completely visible. If the area's ratio differs from the image ratio, an empty space will surround the image.cover
works as CSS propertybackground-size
— shrinks the image (ratio preserved) to the area given byw
andh
so that the area is completely filled. If the area's ratio differs from the image ratio, the image is centered to the area and cropped.crop
cuts off a part specified by image-related coordinatesx
,y
and sizew
,h
.
NOTES:
- If you specify an area size larger than the image for the
contain
andcover
type, then the image will be stretched, not shrunken. - In case of the
crop
option, if the specified area reaches out of the image, then the covered empty space will be a part of the image. - When the
sizing
property is used, itsw
andh
values represent the effective image size. For example, in the following snippet, width and height of the image will both equal to 2 inches and its top-left corner will be located at [1 inch, 1 inch]:
slide.addImage({
path: '...',
w: 4,
h: 3,

Generating sample slides like those shown above is great for demonstrating library features, but the reality is most of us will be required to produce presentations that have a certain design or corporate branding.
PptxGenJS allows you to define Slide Master Layouts via objects that can then be used to provide branding functionality.
Slide Masters are created by calling the defineSlideMaster()
method along with an options object
(same style used in Slides). Once defined, you can pass the Master title to addNewSlide()
and that Slide will
use the Layout previously defined. See the demo under /examples for several working examples.
The defined Masters become first-class Layouts in the exported PowerPoint presentation and can be changed via View > Slide Master and will affect the Slides created using that layout.

master |
string | master slide name | Any pre-defined Master Slide. Ex: { master:pptx.masters.TITLE_SLIDE } |
|
addHeaderToEach |
boolean | add table headers to each slide | Ex: addHeaderToEach:true |
|
addImage |
string | add an image to each slide | Ex: { addImage:{ path:"images/logo.png", x:10, y:0.5, w:1.2, h:0.75 } } |
|
addShape |
string | add a shape to each slide | Use the established syntax. | |
addTable |
string | add a table to each slide | Use the established syntax. | |
addText |
string | add text to each slide | Use the established syntax. |
A minimum column width can be specified by adding a data-pptx-min-width
attribute to any given <th>
tag.
Example:
<table id="tabAutoPaging" class="tabCool">
<thead>
<tr>
<th data-pptx-min-width="0.6" style="width: 5%">Row</th>
<th data-pptx-min-width="0.8" style="width:10%">Last Name</th>
<th data-pptx-min-width="0.8" style="width:10%">First Name</th>
<th style="width:75%">Description</th>
</tr>
</thead>
<tbody></tbody>
</table>
- Default
x
,y
andmargin
value is 0.5 inches, the table will take up all remaining space by default (h:100%, w:100%) - Your Master Slides should already have defined margins, so a Master Slide name is the only option you'll need most of the time
// Pass table element ID to addSlidesForTable function to produce 1-N slides
pptx.addSlidesForTable( 'myHtmlTableID' );
// Optionally, include a Master Slide name for pre-defined margins, background, logo, etc.
pptx.addSlidesForTable( 'myHtmlTableID', { master:pptx.masters.MASTER_SLIDE } );
// Optionally, add images/shapes/text/tables to each Slide
pptx.addSlidesForTable( 'myHtmlTableID', { addText:{ text:"Dynamic Title", options:{x:1, y:0.5, color:'0088CC'} } } );
pptx.addSlidesForTable( 'myHtmlTableID', { addImage:{ path:"images/logo.png", x:10, y:0.5, w:1.2, h:0.75 } } );
Design a Master Slide that already contains: slide layout, margins, logos, etc., then you can produce professional looking Presentations with a single line of code which can be embedded into a link or a button:
Add a button to a webpage that will create a Presentation using whatever table data is present:
<input type="button" value="Export to PPTX"
onclick="{ var pptx = new PptxGenJS(); pptx.addSlidesForTable('tableId',{ master:pptx.masters.MASTER_SLIDE }); pptx.save(); }">
SharePoint Integration
Placing a button like this into a WebPart is a great way to add "Export to PowerPoint" functionality
to SharePoint. (You'd also need to add the 4 <script>
includes in the same or another WebPart)
If you are planning on creating Shapes (basically anything other than Text, Tables or Rectangles), then you'll want to
include the pptxgen.shapes.js
library.
The shapes file contains a complete PowerPoint Shape object array thanks to the officegen project.
<script lang="javascript" src="PptxGenJS/dist/pptxgen.shapes.js"></script>
Scheme color is a variable that changes its value whenever another scheme palette is selected. Using scheme colors, design consistency can be easily preserved throughout the presentation and viewers can change color theme without any text/background contrast issues.
To use a scheme color, set a color constant as a property value:
slide.addText('Hello', { color: pptx.colors.TEXT1 });
The colors file contains a complete PowerPoint palette definition.
<script lang="javascript" src="PptxGenJS/dist/pptxgen.colors.js"></script>
It takes CPU time to read and encode images! The more images you include and the larger they are, the more time will be consumed. The time needed to read/encode images can be completely eliminated by pre-encoding any images (see below).
Pre-encode images into a base64 string (eg: 'image/png;base64,iVBORw[...]=') for use as the data
option value.
This will both reduce dependencies (who needs another image asset to keep track of?) and provide a performance
boost (no time will need to be consumed reading and encoding the image).
Add this to your webpack config to avoid a module resolution error:
node: { fs: "empty" }

Please file issues or suggestions on the issues page on github, or even better, submit a pull request. Feedback is always welcome!
When reporting issues, please include a code snippet or a link demonstrating the problem. Here is a small jsFiddle that is already configured and uses the latest PptxGenJS code.
Sometimes implementing a new library can be a difficult task and the slightest mistake will keep something from working. We've all been there!
If you are having issues getting a presentation to generate, check out the demos in the examples
directory. There
are demos for both Nodejs and client-browsers that contain working examples of every available library feature.
- Use a pre-configured jsFiddle to test with: PptxGenJS Fiddle
- Use Ask Question on StackOverflow - be sure to tag it with "PptxGenJS"
Version 2.0 will be released in late 2017/early 2018 and will drop support for IE11 as we move to adopt more JavaScript ES6 features and remove many instances of jQuery utility functions.
The PptxGenJS library is not designed to replicate all the functionality of PowerPoint, meaning several features are not on the development roadmap.
These include:
- Animations
- Cross-Slide Links
- Importing Existing Presentations and/or Templates
- Outlines
- SmartArt
- Officegen Project - For the Shape definitions and XML code
- Dzmitry Dulko - For getting the project published on NPM
- kajda90 - For the new Master Slide Layouts
- PPTX Chart Experts: kajda90, Matt King, Mike Wilcox
- Everyone who has submitted an Issue or Pull Request. :-)
Do you like this library and find it useful? Add a link to the PptxGenJS project on your blog, website or social media.
Thanks to everyone who supports this project! <3
