## What it is
Carbone is a fast report and document generator that merges JSON data into templates created in Word, Excel, PowerPoint, LibreOffice, HTML, or Markdown to produce PDF, DOCX, XLSX, ODT, PPTX and more. It is embeddable in Node.js, available as a self-hosted Docker edition with a REST API, and also provides document conversion between 100+ formats.

## Use cases
- generate pdf invoices from  data
- convert docx to pdf via api
- fill word templates with  data
- generate xlsx reports from an application
- batch-generate contracts from templates
- convert office documents to pdf in nodejs
- generate multilingual reports with locale-aware dates

## When to choose
- you need to generate reports or documents from JSON using templates designed in Word, Excel, LibreOffice, or HTML
- you want a self-hosted or cloud document generation and conversion API with a REST interface
- you need deterministic, auditable document output for finance, legal, or healthcare workflows
- you want non-developers to edit report templates without touching code

## When to avoid
- you need a pure open-source solution with no licensing tiers, since advanced features require a commercial license
- you only need simple HTML-to-PDF rendering without template merging
- your stack is not Node.js and you cannot run the Docker/REST edition
