What's most interesting and baffling to me is that most people think libreoffice "breaks" things. But so far, every time I looked into it, libreoffice "breaking something" usually flows like this:

• Excel implements some functionality in non-standard ways.
• Calc / libreoffice goes to apply the functionality using the correct, standard way.
• Sheet is now "broken", aka not with the expected data.
• I get yelled at for having dared to use Calc to copy paste some data in a file without even touching scrips or pivot tables or whatever the hell.

Every. Single. Fucking time.

I got to a point where I tell them to wank off if they ask me to do something and I don't have easy access to Windows.
