What it does
Author interactive papers, reports, or presentation-like documents in JSX using Paperjsx patterns when shipping editorial or technical content surfaces.
Files
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-pdfHow it works
1. Build a JSON layout spec matching the schema in references/json-schema.md 2. Write a Node.js script that passes the JSON to the PaperJSX engine 3. Run the script to generate the output file 4. 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.
