Well what are you expecting? Not even between MS Office versions things work sometimes, and after all we’re talking about Excel, the piece of shit software made by some genius team that thinks that having data stored in multiple encodings… Also from the same team you get dates that are stored as strings and parsed live according to whatever computer language / locate you’re using making it a total mess when you’ve to share spreadsheets across languages. Only if there weren’t already good and solid technical solutions used by every developer out there to deal with those kinds of things. UTF-8, ISO dates, timestamps :P
