This is a very simple script that converts Paypal style CSV exports to what YNAB expects.
See more detail on YNAB CSV importing here: https://www.youneedabudget.com/support/article/csv-file-importing
First you need to download the Balance affecting Payments CSV from your Paypal account. Log into your Paypal account and visit this url. Please note this URL is likely to change at some point so it's only here as a convenience.
Clone this repo and npm install to get dependencies.
git clone git@github.com:mansona/paypal-to-ynab.git
cd paypal-to-ynab
npm install
Then all you need to do is run the index.js script with your downloaded CSV file:
node index.js ~/Downloads/PaypalCSVExport.csv
Which will produce a ynab.csv file in the current directory
