Thanks for this.

Here's a fork that turns this into a CLI with various input and output formats: https://gist.github.com/abirchall/54b0f2eb47d02eb3e36e33b3077298a5

[@oravecz] Need to install some non-standard libraries -- any help there?

You can run: pip3 install ofxparse.
You can find info about this library here: https://pypi.org/project/ofxparse/
The underlying code is simple enough, just a bunch of parsing logic specific to the OFX spec.

Nice! I added a -i input argument to @schulzebittar 's script so I can select specific files to convert, if I want. Hope that helps.

I make in more generic to extract as much data from the QFX:

This looks good. I opened a PR to fix a few little bugs nhatkhai/ofx2csv#1
