I have tried your branch of QtXlsxWriter and Qtexcel .
Both projects have problem that the excel file will be damaged when written something to a exist file .The red mark will be lose in below PIC by QtXlsxWriter and Qtexcel

I copy code from projects QtXlsxWriter and Qtexcel and add some code also.
Now some bug are fixed .
I want to patch your project or QtExcel but failed many times.
So i made a new branch on https://github.com/liufeijin/littleQXlsx
below is the the test file and my code zip file
test.xlsx
QXlsx.zip

if you have free time to patch your project , will be great!

For new projects you should not adopt this library but instead use https://github.com/QtExcel/QXlsx
