I have Quickbooks-pro desktop version. How can I import a csv or xls file of transactions in my banking or credit card accounts?

Which QB Desktop year version do you have?

It is ridiculous that Intuit cannot put this feature in QB Desktop to allow a CSV import.  They have this feature in QB Online.

I'm paying a subscription fee for QB Desktop and it doesn't have this feature and no, I am not going to migrate to QB Online.  It doesn't suit my needs.

Customers should not have to buy a third party program to convert CSV to QBO.  Intuit should be putting this feature into the program.
