Faker is an awesome Python library, but I often just want a simple command I can run to generate data in a variety of formats.
With Faker CLI, you can easily generate CSV or JSON data with fields of your choosing.
You can also utilize pre-built templates for common data formats!
By default, fake will generate a CSV output for you. You just specify the number of rows you want and the column types.
fake -n 10 pyint,user_name,date_this_yearBAM! You've got a CSV file with your data.
pyint,user_name,date_this_year
