> Apparently, like many others in this entire thread, you've totally missed the point. I wasn't saying it's "as" high quality as M$ word (although I disagree with the usage of the word high quality here) but just that it is high quality by itself. This is known as an irrelevant conclusion
The entire discussion has been regarding this verbatim quote from the top comment: "open source projects will always provide a lower quality than commercial ones". If you replied regarding some other premise, then you're the one missing the point and changing the topic, not me.
> That's not exactly a fair assessment exercise
It sure is fair to me. Just saying this doesn't make it true. And a reality check is warranted here: "it's not fair" is not going to be a satisfactory response to any user you're trying to win over.
> I'm not sure what format is the original excel file, but xlsb is a proprietary format.
No, it's an open format [1], and LibreOffice supports opening it... with poor quality. And again: even if it was, you're not going to win over or satisfy any users with an "it's a proprietary format so we don't support that many columns" excuse. They expect their office programs to dance around their documents, not the other way around.
