QOds is a free Qt5/C++11 library to work with .ods (OpenDocument Spreadsheet) files. Features: - Create and fill in .ods files with data, including formulas. - Read .ods files, can also calculate the value of formulas. - NO EDITING of .ods files supported, no plans, patches welcome. See "how_to_build.html" for how to build for Windows with MinGW or Visual Studio 2013. Results tested on MS Office 2013 and LibreOffice. For a simple tutorial check the code in app/main.cpp which also shows how to create a sample invoice with formulas and image logos. The resulting invoice file created programmatically with QOds can be viewed at "app/Invoice.ods".
