I did the same lol (via scraping), run every midnight to multiple bank accounts, then sync to google spreadsheet. I was writing web automation scripts the hard way for a while, until I made a tool to simplify the process of writing web automation scripts - https://github.com/tebelorg/TagUI (frankly I am surprised why my banks never banned or send me a letter)

I use Selenium to drive a firefox browser under the assumption that banks don't care enough to detect it: https://github.com/tmerr/bank_wrangler . I am also slightly worried about banks not liking it, but if they do care I guess I will receive a scary cease and desist in the mail and I will cease and desist.

I want to do this too. Details would be handy. Even if its extracting data from PDF statements or saved HTML pages.

I used to use pyofx and a lot of custom scraping to get this, but now I use Plaid. I work at Plaid now, but I used it before I got this position.

Your bank would object to you accessing your own transaction data?

Whole businesses like Yodelee and Plaid do this.
