Qt and xlsx files

[mrdebug]

Hi in order to read and write xlsx file I'm using an QAxWidget ("Excel.Application"). It works but only on Windows. It requires excel installed an it is very slow on create a file with thousand of records.
Has anybody try this library?

That library is outdated.
try https://github.com/QtExcel/QXlsx

It is not as complete as using excel library directly but has a very good support of excel features
