my-expenses CLI on node js

TL;DR

• transform CSV files exported from banks and card providers into CSV files with predefined format: date, amount, category, note;
• substitute merchants with user-defined categories (merchant to category mapping can also be provded with a JSON file);
• print expense data groupped by month or category;
• try out with npx without installing the package.

The problems it is made to solve

• I track my personal expenses on a monthly basis and use a few different means of payment.
• The card provider I use most often lists merchants but no category for each payment and I wanted to map merchant to category only once.
• All of the CSV exports I used to digest into a spreadsheet had more columns that I needed.
