LibXL
LibXL is a C/C++ framework library for reading, writing, and manipulating Microsoft Excel spreadsheets (.xls and .xlsx files) on macOS. It provides a programmatic interface to create Excel workbooks, format cells, insert formulas, and manage sheets without requiring Microsoft Office. Developers embed LibXL into their applications to add Excel file generation and parsing capabilities, making it widely used in data analysis tools, reporting software, financial applications, and enterprise systems that need to export or import spreadsheet data.
AI Recommendation
1 suggestionLibXL is a framework library that ships as part of host applications — it is not a standalone product. If your application uses LibXL and you're running on Apple Silicon, the library must be included in a native Universal Binary build of your host app for full native performance. Contact the developer of the application that uses LibXL and ask whether they ship a native Apple Silicon build. If the host application was built with a recent version of LibXL and compiled with a modern development toolchain (Xcode 12.2 or later with Apple Silicon support), it should include a native LibXL framework. If your host app is still Intel-only under Rosetta, updating the host application to its latest version should pull in a native LibXL build automatically — you do not need to update LibXL separately. If the host application has not been updated to native Apple Silicon yet, contact the vendor to ask about their timeline, particularly as Apple is removing Rosetta 2 in macOS 28 (September 2028), when any Intel-only build will stop launching.
