Since Intuit announced that Mint was going away, I’ve spent several months investigating how to import my Mint data into Firefly-iii, an open source, self-hosted budgeting software. It seemed like a perfect fit. I would fully own the data and get to build whatever tooling I want on top.
However, before we can get there, we need to have cleaned and accurate data from Mint. As it turns out, Mint’s data actually had some errors in it that required me to go back years and fix them.
