Version 2.0 Feature

High-Precision PDF Export

Generate pixel-perfect PDFs directly from Excel workbooks. Fast native C++ conversion without external tools.

📑

Simultaneous Excel & PDF Output with a Single Codebase

Traditional enterprise architectures often require separate rendering pipelines or external server processes to generate PDF reports from spreadsheet templates.
With osbxl 2.0, you can export both native Excel workbooks and high-precision PDFs directly from the same in-memory workbook.
Eliminates dependencies on external utilities or virtual printer drivers, powered by our high-performance native C++ engine.

📐 High Excel Fidelity

Fonts, cell borders, background colors, page setup, print areas, and page breaks closely aligned with Excel standards.
