Templates to
PDF & Excel,
on demand.
Upload Word or Excel templates, POST JSON, receive production documents. Self-host the full stack when data must stay inside your network.
Works with any language or framework
From template to production output
Watch the four-step workflow that turns Word or Excel templates and JSON data into PDF, DOCX, Excel, or ZIP output.
New project
Name your project.
Groups your templates, API keys, and generation history.
From data to PDF in seconds.
Qorstack Report turns JSON data and your templates into pixel-perfect PDFs via a simple REST API.
- Create a project and get your API key
- Upload or design a PDF template
- POST JSON data to the render endpoint
- Receive a generated PDF instantly
Manage templates visually,
map variables automatically.
Upload your DOCX or XLSX template and Qorstack Report detects the fields your API payload needs. Fill values visually, test the output, then copy SDK or REST examples that match the same payload.
- Detect variables, tables, images and codes
- Configure render payload visually
- Copy SDK and REST examples
{
"templateKey": "invoice-template",
"replace": {
"customer_name": "Acme Co., Ltd.",
"invoice_no": "INV-2026-001"
},
"table": [...],
"image": { ... }
}Current SDK examples, copy-ready.
Install the qorstack-report-sdk, send the same payload your template builder uses: variables, tables, QR codes, barcodes, password protection, and watermark settings.
Any font,
your way.
Use Google Fonts out of the box, mount a config file, or upload WOFF/WOFF2 directly through the dashboard — fonts render identically in every generated document.

Excel Report
Auto-filter, frozen headers, totals, number formats, and sheet splitting.
Protected Contract
PDF password permissions, watermark text, and ZIP packaging.
Shipping Label
Barcode generation with format, size, color, and readable text.
Ticket QR
QR codes from URLs, payloads, colors, backgrounds, and embedded logos.
