ExpenseTracker

Personal tool I use to map bank accounts reports and upload them to a google spreadsheet.

Warning

the project is a personal tool

it just handles the type of bank accounts I need, it is not thougth as a "all bank accounts" tool

Handled bank accounts

  • revolut
  • sella
  • widiba

What problem does it solve?

I have more than one bank account, my expenses are spread through them. My girlfirend has another bank account.

We would like to aggregate our expesnes in a single place in order to be able to check and monitor them.

We chose google spreadsheet to aggregate expenses, beacuse it has different clients (mobile/web) and it is easy to use and edit manually if needed.

Given multiple bank accounts reports, this script map them into a model we choose to use to represent expenses on the spreadsheet, and uplaod the expenses to the google spreadsheet.

The process is not yet fully automated, because I have to run manually the script after I download manually the exports (not the best but I am working on making it better)

Highlight of the project

  • The script is configurable using a json file config/config.json
