\title Formulas Example
\brief This is a simplest Qt Xlsx example.
\ingroup qtxlsx-examples
This example demonstrates how to create a new
.xlsx file containing formulas
with Qt Xlsx Library. So lets see how this is achieved.
This creates a new instance of the all important Document
class which gives you access to the Excel workbook and worksheets.
\snippet formulas/main.cpp 0
A default worksheet have been created by Document. Let's start
by adding some basic formulas.
\snippet formulas/main.cpp 1
Then add one array formula.
\snippet formulas/main.cpp 2
Now save the file and all its components.
\snippet formulas/main.cpp 3
