ts-pptxPowerPoint decks from TypeScript

Write .pptx packages that open cleanly in PowerPoint, read them back, and turn one into the script that would rebuild it.

Get started

API reference

Write

Slides, masters and themes, charts with real embedded workbooks, tables, groups, connectors, gradients, images in shapes, OLE objects, 3D models and LaTeX maths. Emitted as OOXML, validated against the ECMA-376 schemas.

Your first deck

Read

Open an existing package and inspect it through typed accessors. What the reader cannot yet see is measured and published rather than guessed at.

Reading a deck

Convert to a script

Turn a .pptx into the TypeScript that would rebuild it, with a fidelity note for everything the conversion could not carry.

pptx → script

Runs where you do

One ESM build. Node 24+, where require() reaches it through Node's own interop; any bundler; a browser, straight from an ESM CDN if you have no build step. No office application in the loop anywhere.

Where it runs

Install

bash

pnpm add pptx-ts

Installation covers npm, CommonJS, the optional math dependencies and the package's other name.
