This is a small utility to work with csv files. It is really just a thing wrapper around pandas.
I'm using venv which will be located in ./venv. Do install requirements (including for development):
python3 -m venv venv
source ./venv/bin/activate
python3 -m pip install -r requirements.txtThere is a small wrapper script, ./csv-util. Symlink into to your path and it will source the venv and run the python script.
