This is not tax advice and we cannot give you any. What counts as a taxable event, how gains are worked out and what you owe all depend on where you live, and the rules change. The file is a record of what happened. It is not a completed return and it is not a legal opinion. Take it to somebody qualified in your country.
It only knows what you connected. Trades you made somewhere else, or before you started using this, or by hand on an exchange you never linked, are not in the file and cannot be. It is a record of your activity here, not a complete picture of your finances, and treating it as the latter would be a mistake.
Tax software changes its mind about formats. We keep the layouts current and we will add new ones when they are needed, but we do not control those products and we are not going to promise that any particular one will accept a file without complaint. If a layout you need is missing, tell us and we will look at adding it.
