I guess you best try to address Greg Green directly. As far as I see R34 beta is out. If you see problems or have wishes you might use
https://github.com/ggreen86/XLSX-Workbook-Class/issues. Always remember - one problem - one issue. :)
Thanks Lutz, will do.
The repo is a catastrophe, I have given up to talk him into a good git repo (I even provided him code to rebuild his zips into a meaningfully repo), but he his work is not.
Perhaps I can bring you a very nice NZ medicinal beverage when next in your direction, in exchange for the same for my private code built up over 30 years(!)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
