1) Chase Credit Card supports direct-connect to Moneydance.
2) If you don't want to set up direct-connect, download the QFX file format from the Chase Credit Card website. It is superior to the QIF file format.
The last time I looked at a Chase QIF file download it was incorrectly formed, it was missing the caret character that signifies the end of each transaction record. I suspect that Chase have not correctly the problem.
