xlnt

Introduction

xlnt is a C++14 library for reading, writing, and modifying XLSX files as described in ECMA 376. The API is roughly based on openpyxl, a python library for reading and writing xlsx/xlsm files. This is still very much a work in progress, but the core development work is complete.

Usage

Including xlnt in your project

// with -std=c++14 -Ixlnt/include -Lxlnt/lib -lxlnt
#include <xlnt/xlnt.hpp>

Creating a new spreadsheet and saving it

xlnt::workbook wb;
xlnt::worksheet ws = wb.get_active_sheet();
ws.get_cell("A1").set_value(5);
ws.get_cell("B2").set_value("string data");
ws.get_cell("C3").set_formula("=RAND()");
ws.merge_cells("C3:C4");
ws.freeze_panes("B2");
wb.save("book1.xlsx");

Opening an existing spreadsheet and printing all rows

xlnt::workbook wb2;
wb2.load("book2.xlsx");

// no need to use references, iterators are only wrappers around pointers to memory in the workbook
for(auto row : wb2["sheet2"].rows())
{
    for(auto cell : row)
    {
        std::cout << cell << std::endl;
    }
}

Building

xlnt is regularly built and passes all 200+ tests in GCC 4.8.2, MSVC 14, and Clang (using Apple LLVM 7.0).

Build configurations for Visual Studio 2015, GNU Make, and Xcode can be created using cmake and the cmake scripts in the project directory, cmake.

In OSX, with Xcode:

mkdir build
cd build
cmake -G Xcode ../cmake
open xlnt.xcproject

In Windows, with Visual Studio 2015:

mkdir build
cd build
cmake -G "Visual Studio 14 2015" ../cmake
start xlnt.sln

In Linux or OSX, with GNU Make:

mkdir build
cd build
cmake -G "Unix Makefiles" ../cmake
make

Dependencies

xlnt uses the following libraries, which are included in the source tree (pugixml and cxxtest as git submodules) for convenience:

• miniz v1.15_r4 (public domain/unlicense)
• pugixml v1.6 (MIT license)
• cxxtest v4.4 (LGPLv3 license [only used for testing, separate from main library assembly])
