Structured application data
DELIVERABLE INFRASTRUCTURE FOR AI PRODUCTS
Ship the native deliverable your AI product is judged by.
Turn structured product output into editable PPTX, DOCX, XLSX, and PDF files your customers can present, review, calculate with, and keep — inside the runtime you control.

EXECUTION ARCHITECTURE
One runtime boundary from request to artifact.
Your application owns data, orchestration, storage, and delivery. PaperJSX turns validated structured input into a native file and returns diagnostics to the caller.

INTEGRATION SURFACES
Use the interface your platform can operate.
Start with TypeScript packages, call the CLI from an existing pipeline, or expose local tools through MCP.
TypeScript packages
Keep document generation in a testable Node.js module beside your application code.
import {
PaperEngine,
compilePresentationSpec,
} from "@paperjsx/json-to-pptx";
const doc = compilePresentationSpec(spec);
const file = await PaperEngine.render(doc);CLI
Render and validate from local scripts, fixture jobs, and CI.

Connect compatible agent workflows to a local PaperJSX process over stdio.

}VALIDATION MODEL
Make the render boundary observable.
Pair schema validation, engine diagnostics, and repository fixtures with the acceptance criteria your product owns.
| Stage | Check | Caller outcome |
|---|---|---|
| Before render | Validate structured input | Return named input findings |
| During render | Capture engine diagnostics | Record warnings or terminate the call |
| After render | Run structural or visual fixture checks | Advance or stop the application workflow |
Render a file from your own JSON.
The playground runs the same engines as the packages.
