## 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
|
|
```
|
|
|
|
