Hi @Alexandru Gavrisan,
According to your description, I understand that you want to automatically download a .csv file from SharePoint list attachment to a local drive in a regular time or when the file is changed/modified/updated. As per my knowledge, it can be achieved via Power Automate flow. As I'm not an expert in this product, I suggest you go to the dedicated community here: https://community.powerplatform.com/forums/thread/?groupid=46ce02a3-e1a7-4176-81fc-d93a4001d287. Experts there will give you instant help.
Thanks.
