The .xlsx file format is the native format used by Microsoft(R) Excel(TM) since version 2007.
The library was written with the following goals in mind:
- primary focus on data values organized in tables, on not layout or graphics
- written in standard C, but allows being used by C++
- simple interface
- small footprint
- portable across different platforms (Windows, *nix)
- minimal dependancies: only depends on expat (only for reading) and libzip (which in turn depends on zlib)
- separate library for reading and writing .xlsx files
Also includes command line tools to convert between .xslx and CSV files.
