OpenXLSX is a C++17 library for reading, writing, creating, and modifying Microsoft Excel .xlsx files. It is built with CMake and integrates easily into C++ projects as a standalone or monolithic library.
Use cases
- read data from xlsx files in C++
- generate Excel reports programmatically
- modify existing spreadsheets without Excel installed
- create xlsx files from application data
- parse spreadsheet cells and values in C++
When to choose
- you need native C++ Excel file support with no Excel/COM dependency
- you want a lightweight, permissively licensed (BSD-3) xlsx library
- your project uses CMake and C++17
When to avoid
- you need advanced features like tables, filters, or full hyperlink support
- you work primarily in Python or .NET where richer spreadsheet libraries exist
- you need to handle very large files with low memory usage
