xlnt is a C++14 library for reading, writing, and modifying xlsx files as described in [ECMA 376 4th edition](http://www.ecma-international.org/publications/standards/Ecma-376.htm). The API was initially based on [openpyxl](https://bitbucket.org/openpyxl/openpyxl), a Python library to read/write Excel 2007 xlsx/xlsm files, which was itself based on [PHPExcel](https://github.com/PHPOffice/PHPExcel), pure PHP library for reading and writing spreadsheet files. xlnt is still very much a work in progress, but the core development work is complete. For a high-level summary of what you can do with this library, see [here](http://xlnt.readthedocs.io/en/latest/#summary-of-features).
xlnt uses continous integration (thanks [Travis CI](https://travis-ci.org/) and [AppVeyor](https://www.appveyor.com/)!) and passes all 270+ tests in GCC 4, GCC 5, VS2015 U3, and Clang (using Apple LLVM 8.0). Build configurations for Visual Studio 2015, GNU Make, and Xcode can be created using [cmake](https://cmake.org/) v3.1+. A full list of cmake generators can be found [here](https://cmake.org/cmake/help/v3.0/manual/cmake-generators.7.html). A basic build would look like (starting in the root xlnt directory):
The resulting shared (e.g. libxlnt.dylib) library would be found in the build/lib directory. Other cmake configuration options for xlnt can be found using "cmake -LH". These options include building a static library instead of shared and whether to build sample executables or not. An example of building a static library with an Xcode project:
xlnt requires the following libraries which are all distributed under permissive open source licenses. All libraries are included in the source tree as [git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules#Cloning-a-Project-with-Submodules) for convenience except for pole and partio's zip component which have been modified and reside in xlnt/source/detail:
Additionally, the xlnt test suite (bin/xlnt.test) requires an extra testing library. This test executable is separate from the main xlnt library assembly so the terms of this library's license should not apply to users of solely the xlnt library:
