xlnt
====

## Introduction
xlnt is a C++14 library for reading, writing, and modifying xlsx files as described in [ECMA 376](http://www.ecma-international.org/publications/standards/Ecma-376.htm). The API is generally based on [openpyxl](https://bitbucket.org/openpyxl/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
```c++
// with -std=c++14 -Ixlnt/include -Lxlnt/lib -lxlnt
#include <xlnt/xlnt.hpp>
```

Creating a new spreadsheet and saving it
```c++
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
```c++
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).

Workspaces for Visual Studio 2015, GNU Make, and Xcode can be created using GENie and the genie.lua script in the build/genie directory. 

GENie binaries and source are currently available [here](https://github.com/bkaradzic/genie).

In Windows, with Visual Studio 2015:
```batch
cd build/genie
genie vs2015
start vs2015/xlnt.sln
```

In Linux or OSX, with GNU Make:
```bash
cd build/genie
genie gmake
cd gmake && make
```

In OSX, with Xcode (Xcode 4 projects can be opened in Xcode 7.0)
```bash
cd build/genie
genie xcode4
open xcode4/xlnt.xcworkspace
```

For users who prefer CMake, cmake scripts are provided in build/cmake. To use this system, a build might look like:
```bash
cd build/cmake
mkdir build
cd build
cmake ..
make
```

## Dependencies
xlnt uses the following libraries, which are included in the source tree (pugixml and cxxtest as [git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules#Cloning-a-Project-with-Submodules)) for convenience:
- [miniz v1.15_r4](https://code.google.com/p/miniz/) (public domain/unlicense)
- [pugixml v1.6](http://pugixml.org/) (MIT license)
- [cxxtest v4.4](http://cxxtest.com/) (LGPLv3 license [only used for testing, separate from main library assembly])
