No, and even if you did, it probably wouldn't work. The QFX format is an Intuit proprietary format and Quicken confirms that the financial institution that the data is from is a licensed data provider, so you can't "fake" one. You can however, tweak the QIF file using the instructions in this post to make it usable: https://qlc.intuit.com/post/show_post_full_view/dQMNaWtX4r3OK1acfArQA8
Make sure you have a recent backup in case something goes wrong and you need to revert to the backup.
I am still using Q2005 and my bank only has qfx as export and Q2005 only wants qif. I purchased iBank and it opens my bank's qfx data and from there I can export these now iBank transactions as qif's which Q2005 likes. Problem solved. Although I now have my bank and finance data on 2 computers and 2 different pieces of software, I guess it's crash insurance :-)
