It is already many years ago since that I started to do certain jobs in Libre Office (back then it was still OpenOffice.org) even if I had MS Office. I mean, it was better at certain tasks and costed nothing.
In all fairness, back them I also had to use MS Office for certain other tasks, but luckily I don't need that anymore.
Now there is Confluence instead however to mangle our docs and waste our time.
EDIT: rather than downvoting, maybe you could engage? Following the thread back the question was about accountants using Excel and then someone weighed in that they use Libre/open office. I have never seen an accountant use libre office for accounts work, hence my question. Are you an accountant who moved from Excel because of whatever, or was your comment irrelevant?
I'm not, and I'm sure if I had to use Excel every day I would adapt. But both Windows and Office reached their peak at around 2003 and it's been downhill ever since. I quite liked Windows 2000 Pro as a desktop.
I'm sure he's not, I am one and I have to use excel though I also hate the ribbon but I just use excel 2010 + ubitmenu and will continue to use that version or similar until I can't anymore
I had used excel 2003 until I was forced to use win 10 at which point it barely functioned anymore (i.e., it worked great in win 7)
I still miss excel 2003, it has been downhill from there
As for accounting software, they all mostly stink though serve a purpose in larger companies where you need some degree of separation of duties to reduce (at least in appearance as much internal control is theatre) error/theft risk...
