01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads paperjsx automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

PaperJSX Document Generation

Generate professional documents from JSON layout specs. PaperJSX is generation-only — it creates new files, it does not edit existing ones.

Triggers

Use this skill when the user asks to:

Create a presentation or generate slides
Make a PPTX or PowerPoint file
Create a Word document or DOCX
Generate an Excel spreadsheet with charts
Create a JSON to PPTX, JSON to DOCX, or JSON to XLSX file
Generate a PDF invoice, report, or chart document

Install

Install the format-appropriate package:

# Presentations
npm install @paperjsx/json-to-pptx

# Word documents
npm install @paperjsx/json-to-docx

# Spreadsheets
npm install @paperjsx/json-to-xlsx

# PDF documents
npm install @paperjsx/json-to-pdf

How it works

Build a JSON layout spec matching the schema in references/json-schema.md
Write a Node.js script that passes the JSON to the PaperJSX engine
Run the script to generate the output file
Validate the output file exists and is non-zero bytes

Do not write imperative PaperJSX API code. The execution model is always: JSON spec in, document file out.

Example: PPTX generation

import { PaperEngine } from "@paperjsx/json-to-pptx";
import fs from "node:fs";

const spec = {
  type: "Document",
  meta: { title: "Q4 Review" },
  slides: [
    {
      type: "Slide",
      children: [
        { type: "Text", content: "Q4 2025 Business Review", style: { fontSize: 36, bold: true } }
      ]
    }
  ]
};

const buffer = await PaperEngine.render(spec);
fs.writeFileSync("presentation.pptx", buffer);
console.log("Generated presentation.pptx");

Example: DOCX generation

import { renderToDocx } from "@paperjsx/json-to-docx";
import fs from "node:fs";

const result = await renderToDocx({
  type: "DocxDocument",
  pageSize: "a4",
  orientation: "portrait",
  pages: [
    {
      elements: [
        { type: "heading", level: 1, text: "Quarterly Report" },
        { type: "paragraph", text: "Section content here." }
      ]
    }
  ]
});

fs.writeFileSync("report.docx", result.buffer);
console.log("Generated report.docx");

Example: XLSX generation

import { SpreadsheetEngine } from "@paperjsx/json-to-xlsx";
import fs from "node:fs";

const spec = {
  meta: { title: "Revenue Data", creator: "PaperJSX" },
  sheets: [{
    name: "Revenue",
    rows: [
      { cells: [{ value: "Quarter" }, { value: "Revenue" }] },
      { cells: [{ value: "Q1 2026" }, { value: 420000 }] },
      { cells: [{ value: "Q2 2026" }, { value: 510000 }] }
    ]
  }]
};

const buffer = await SpreadsheetEngine.render(spec);
fs.writeFileSync("revenue.xlsx", buffer);
console.log("Generated revenue.xlsx");

Validation

After generating any file, always verify:

import fs from "node:fs";

const stats = fs.statSync("output.pptx");
if (stats.size === 0) {
  throw new Error("Generated file is empty");
}
console.log(`Output file: ${stats.size} bytes`);

If the engine throws an error, surface the full error message to the user.

Schema reference

See references/json-schema.md for the complete JSON layout spec schema for all supported formats.
