...I have none problem...
Good for you. And it can work and often will. But you are likely to run into problems if you do not use Euro (only), nevermind if you use several languages and locales. In the English version SH3D uses comma as thousands separator and period/full-stop as decimal separator. Excel/LO/OO use computer locale. And in Excel I have not found a way of changing comma/full stop in the import wizard. But I think feature request 890 at least could solve most of the problem. For those of us who do not have mononational computers, that is 
..increasingly surprising that a free and open source program only works properly with expensive closed source software such as Windows and Excel...
Having grown up with Unix I love Linuxe and have used it on and off for very many years. Fast, open, flexible, easily customised, but it comes at a cost. There are either issues that do not work as they should, graphic drivers, network cards, printers, scanners ... or something. Not to forget the mess with trying to use Wine for special applications. As you say, there are always workarounds but I simply do not have the time. There is a reason I would hesitate recommending Linux to inexperienced computer users. Before you know it, you end up having to use the command line to perform mondane tasks. That said, do not forget that Windows have serious disadvantages too. I could write a list about everything that is wrong with Windows, especially 10.As for the SH3D installation issues, I have not tried and cannot tell. But I am positively surprised at the all-in-all few problems with SH3D running on many Linux distros and Windows/MacOS versions.
But when it comes to interaction with Excel and .csv, I hardly think SH3D is to blame. My experience is that Excel is the least easy to exchange SH3D furniture lists. LibreOffice / OpenOffice work reasonably well (better import dialogue), but for my setup, Gnumeric (a version ported from Linux to Windows) is the best. So there you go. Maybe I should upgrade to Linux after all...
ok
