Boegbeeld Creative Company The officially supported way is using the bunq app on your phone or tablet, as bunq web does not have such functionality at the moment. In the phone app, you can export bank statements for a time span that you can choose yourself (so you could set it to Jan 1st 2019 to Dec 31st 2019). They can be exported in different formats, for example PDF or CSV that you can use in Excel.
There are some third party apps that allow you to export statements on your desktop computer from your bunq accounts. For example bunqDesktop or MoneyMoney. I personally use both of them and think they are great, but they're 3rd party products and not made by bunq themselves.
