pptx-builder

Generate beautiful PowerPoint presentations from AI-generated JavaScript code — instantly via CLI.

The Idea

Ask any AI (ChatGPT, Claude, Gemini) to write a pptxgenjs script.
Save it as a .js file.
Run one command.
Get a .pptx file in your folder.

npx pptx-builder my_presentation.js

Requirements

• Node.js installed (any recent version)
• That's it. Nothing else.

Usage

Step 1 — Ask AI for code

Open ChatGPT, Claude, or Gemini and paste this prompt:

You are a PowerPoint presentation code generator using the pptxgenjs library.

Generate a complete Node.js script using pptxgenjs that creates a professional
PowerPoint presentation about [YOUR TOPIC HERE].

Rules:
- Use only 6-digit hex colors (e.g. FF0000). No 8-digit, no transparency.
- Do NOT use pptxgen.ShapeType — use plain strings like "rect" instead.
- All content inside one single file, no imports except pptxgenjs.
- Last line must be: pptx.writeFile({ fileName: "output.pptx" });
- Do not wrap in markdown or backticks, return raw JS only.

Make it visually beautiful with dark background, colors, and good layout.
Include at least 8 slides.

Step 2 — Save the code

Copy AI output → save as presentation.js

Step 3 — Run

npx pptx-builder presentation.js

Step 4 — Open your file

output.pptx appears in the same folder. Open in PowerPoint or Google Slides.

Example Output

const pptxgen = require("pptxgenjs");
const pptx = new pptxgen();

let slide = pptx.addSlide();
slide.background = { color: "0F0F1A" };
slide.addText("My Presentation", {
  x: 1, y: 2, w: 8, h: 1.5,
  fontSize: 44, bold: true,
  color: "7C83FD", align: "center"
});

pptx.writeFile({ fileName: "output.pptx" });

Why use pptx-builder instead of pptxgenjs directly?

| | pptxgenjs alone | pptx-builder | |---|---|---| | Need to install anything | Yes | No (npx handles it) | | Works from any folder | No | Yes | | AI-ready prompt included | No | Yes | | Beginner friendly | No | Yes |

Common Errors & Fixes

| Error | Fix | |---|---| | 8-digit color warning | Use 6-digit hex only e.g. FF0000 | | ShapeType.rect error | Use plain string "rect" instead | | pptx is not defined | Declare const pptx = new pptxgen() at top | | File path error | Use filename only in writeFile, not full path |
