What is OpenXLSX?
OpenXLSX is a C++ library that enables reading, writing, creating, and modifying Microsoft Excel files in the .xlsx format. It solves the problem of programmatically interacting with Excel spreadsheets from C++ applications, offering a native alternative to libraries in other languages like Python or Java.
C++ developers who need to generate reports, import/export data, or automate Excel file manipulation within their applications, particularly in performance-sensitive or cross-platform environments.
Developers choose OpenXLSX for its speed, minimal dependencies, and comprehensive feature set—including support for cell formatting, merging, and comments—all while maintaining a clean, modern C++ API that integrates easily with CMake-based projects.
