Download data from in OFX format

...or how to grab transaction data out of AIB's online interface, and format it into OFX file.

NOTE: Last AIB login update (Feb' 2021) made me realise how brittle the overall machinery here is. The code that works around Web Storage API use is ugly and likely to break. The most likely road forward for this project is to decouple it into ofxstatement plugin and (maybe) Selenium-powered CSV acquisition script. The former will be easy, the latter will most likely be a nightmare to maintain and install, unless you enjoy having your banking details pipe through an arbitrary docker image.

Time will tell.


python3 -mvenv aib2ofx
source aib2ofx/bin/activate
pip3 install aib2ofx

This will create a virtualenv for aib2ofx, fetch its code then install it with all dependencies. Once that completes, you'll find aib2ofx executable in the bin directory of this new virtualenv.


Create a ~/.aib2ofx.json file, with AIB login details. Set the permission bits to 0600 to prevent other system users from reading it.

touch ~/.aib2ofx.json
chmod 0600 ~/.aib2ofx.json

It has a JSON format, single object with one key per AIB login you want to use.

    "bradmajors": {
        "regNumber": "12345678",
        "pin": "12345"

The fields are as follows:

  • regNumber > Your AIB registered number.

  • pin > Your five digit PIN.

You can put more than one set of credentials in the file; the script will download data for all accounts for all logins.

    "bradmajors": {
        "regNumber": "12345678",
        "pin": "12345"
    "janetweiss": {
        "regNumber": "87654321",
        "pin": "54321"

Note that there's no comma after the last account details.

Once you've prepared that config file, run:

aib2ofx -d /output/directory

The script should connect to AIB, log in using provided credentials, iterate through all accounts, and save each of those to a separate file located in /output/directory.


There is none.

I've written that script with my best intentions, it's not malicious, it's not sending the data anywhere, it's not doing anything nasty. I'm using it day to day to get data about my AIB accounts into a financial program that I use. It should work for you as good as it works for me. See the LICENSE file for more details.


aib2ofx works only with python 3.

In order to set up a dev environment clone the repository, get poetry and run poetry install. This will create a virtualenv with all dependencies installed. You can activate it with poetry shell.
