Built around JSZip and xml2js

High-level classes for semantic convenience

Direct access to the OpenXML structure

Classes for handling relations and embeddings

Constructor takes a PPTX file as template

Extensive unit tests for quality and examples

API documentation and examples

"Clean room" development under Microsoft CNS

Same library used in production by Protobi

Contributing Sponsorship

Private open-source access (under NDA)

Deploy via private NPM

Professional support, direct from development team

Fork repo and make private extensions .

Ability to contribute pull requests to main branch.

Contribute to development agenda

Cost

$14,800 for perpetual OEM license for commercial use.

$4,800 per year access for maintenance releases

High and low-level access

Use high-level Javascript classes for simple semantic access:

shape.getGeometry().shape('trapezoid')

Or access the XML directly to do anything that the OpenXML allows, even if it's not yet in the high-level API:

shape.child('a:prstGeom').attr('prst', 'trapezoid')

This way, you're never at the mercy of another development team to add an obscure feature that you simply require.

Basic example

// read existing template
fs.readFile(INFILE, function (err, data) {
    if (err) throw err;
    var pptx = PPTX();
    pptx.load(data, function (err) {

    // create new slide from layout
    var slide = pptx.addSlide("slideLayout3");

    // edit shape text in place
    slide.getShapes(0).text("Revised text");

    // create new shape
    var shape = slide.addShape();
    shape.text("72pt Red Arial");

    shape.getShapeProperties()
        .x(PPTX.emu.inch(1))
        .y(PPTX.emu.inch(2))
        .cx(PPTX.emu.inch(7))
        .cy(PPTX.emu.inch(1))
        .prstGeom('rect')
        .setNoFill(true)
        .setNoEffects(true)

    shape.getStyle()
        .fillSchemeColor('lt2')
        .fontSchemeColor('accent2');

    // detailed control of text
    shape.getTextBody()
      .getParagraphs()[0]
      .getRuns()[0].getProperties()
        .size(7200)
        .setTypeface('Arial')
        .italic('1')
        .bold('1')
        .underline('sng')
        .strike('sngStrike')

    shape.getTextBody().getBodyProperties()
        .wrap('none')
        .attr('rtlCol', '0') // direct XML
        .anchor('right')

    // Use JSZip API to stream/zip/save...
    fs.writeFile(OUTFILE, pptx.toBuffer());
