One for my reference only I should think. My bank only gives me statements as PDFs, my accountant wants .csv files.
The way to do it is the following:
Log on to the bank account.
Click on the Services link, then Télécharger ses relevés de comptes. You can leave all the settings as they are, it will download the last 30 days.
Unfortunately, despite the settings offered it only works for the last 30 days, so don't forget to do it.
