unable to build QtXlsx examples using Qt creator

Error: Unknown module(s) in QT: xlsx

I have copy pasted qmake config file in pro file. Still it shows the above error

[europaa]

it means that you haven't installed the xlsx module into your qt installation.
the line "QT+=xlsx" instructs the qmake to look for an xlsx module, which generates the error you've seen if it fails to find one.
and the line that begins with "#include..." would not do what you believe it to do, since the "#" symbol starts a comment in *.pro files.
i recommend you to read the documentation for typical usage scenarios thoroughly: https://github.com/dbzhang800/QtXlsxWriter/blob/master/README.md

Thank you for your prompt reply.
When I open the qtxlsx.pro and build it using Qt creator is gives error: Executable C:\build-qtxlsx-Desktop_Qt_5_3_MSVC2010_OpenGL_32bit-Debug\examples\xlsx\calendar\debug\calendar.exe does not exist.

do a "make clean" and "rebuild all"

Hi, If your Qt5 is download and installed directly from qt-project, thennmake install
is needed just after you built the library.

Otherwise, if your Qt5 is compiled by yourself, nmake install isn't needed.
