made a little streamlit app that turns my bank export into a spending chart

Followed the Streamlit lesson and then just swapped their sample sales file for my own bank CSV. Everything stays on my laptop which was the whole point, I'm not uploading my statements to some random budgeting site.

Took about an hour and 50 minutes of that was fighting the date column because my bank exports dates as "03 Oct 2026" like a psychopath.

Next job is categories so I can see exactly how much I spend on Deliveroo. Already scared.
