xlnt
====

## Introduction
xlnt is a C++11 library for reading, writing, and modifying xlsx files. The API is generally based on [openpyxl](https://bitbucket.org/openpyxl/openpyxl), a python library for reading and writing xlsx/xlsm files. It is still very much a work in progress, but the core development work is complete.

## Usage
Including xlnt in your project
```c++
// with -Ixlnt/include
#include <xlnt/xlnt.hpp>
```

Creating a new spreadsheet and saving it
```c++
xlnt::workbook wb;
xlnt::worksheet ws = wb.get_active_sheet();
ws.cell("A1").set_value(5);
ws.cell("B2").set_value("string data");
ws.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.get_value().to_string() << std::endl;
    }
}
```

## Building
xlnt is regularly built and passes all 200+ tests in GCC 4.8.2, MSVC 12, and Clang 3.4.

Workspaces for Visual Studio 2013, and GNU Make can be created using the development version of premake (currently available [here](https://bitbucket.org/premake/premake-dev), binaries [here](http://sourceforge.net/projects/premake/files/Premake/nightlies/)) and the premake5.lua script in the build directory. XCode workspaces can be generated using premake4.lua and premake4 (binaries [here](http://sourceforge.net/projects/premake/files/Premake/4.3/)).

In Windows, with Visual Studio 2013:
```batch
cd build
premake5 vs2013
start vs2013/xlnt.sln
```

In Linux, with GCC 4.8:
```bash
cd build
premake5 gmake
cd gmake
make
```

In OSX, with Clang 3.4 (can also use gmake as described above):
```bash
cd build
premake4 xcode4
open xcode4/xlnt.xcworkspace
```

## Dependencies
xlnt uses the following libraries, which are included in the source tree for convenience:
- [miniz v1.15_r4](https://code.google.com/p/miniz/) (public domain/unlicense)
