Since AIB now allow small businesses to use the Personal Internet Banking system, instead of the archaic IBB system, it's become a lot easier to export transactions as CSV.
This script will convert the AIB CSV into a format that can be uploaded to FreeAgent.
It's built on top of the awesome Marathon Swift scripting system.
Visit the Marathon Github page for installation instructions.
git clone git@github.com:appsandwich/aib2fa.git
cd aib2fa
marathon install aib2fa
aib2fa /path/to/your/file.csv
This will generate a new file at /path/to/your/file-converted.csv
