Carbone
Template-based document generation engine that renders DOCX, XLSX, ODP, and PDF files by merging JSON data into Office document templates using a simple mustache-like syntax, available as a self-hosted library or cloud API.
Best When
Your documents start as Word/Excel templates created by designers or business users, and you need to merge data into them programmatically — especially common for contracts, invoices, and reports.
Avoid When
Your document structure is highly dynamic and can't be expressed as a template, or your source is HTML rather than Office documents.
Use Cases
- • Generating PDF reports by merging data into Word document templates designed by non-developers
- • Contract and agreement generation from dynamic data merged into standard templates
- • Invoice and financial document generation maintaining exact branding from Office templates
- • Batch document generation — processing hundreds of documents with different data in parallel
- • Multilingual document generation from same template with different locale data
Not For
- • Pixel-perfect HTML-to-PDF conversion (use DocRaptor or Browserless for HTML sources)
- • Complex dynamic layouts where structure changes based on data (templates are fixed structure)
- • Real-time document generation with sub-500ms latency (rendering takes time)
- • Applications without ability to create/manage Office document templates
