@PatMyron is there a reason for this?

[PatMyron]

@kmcquade fixes #88 (cron updating data again); currently fails with ModuleNotFoundError: No module named 'pandas'

spent hours trying to fix .xlsx writing in Github actions instead, but .csv seems sufficient if .xlsx causes that much trouble in Github actions

[kmcquade]

It won't return the module not found error if you run pipenv install --dev first :)

[PatMyron]

That works locally, but it's been running into No module named 'pandas' even after pipenv install --dev in Github actions:
