This is the big advantage of hledger. It has two ways of translating csv into journal form - one simple and one more complicated, but very flexible.

I find it best to have a separate journal for each downloaded account. I just include them into a master journal (along with a manual entry journal) and generate reports from that.

I also use git so I can roll back the latest import, if something goes wrong - but that hasn’t happened yet.
