I am working on a property sale dataset. Geographic coordinates are needed to make maps on Tableau. To convert addresses in original dataset into geographic coordinates, I use google maps geocoding key and python script. Free limits are 2,500 per day. Also, we can also adopt google sheet with geocode add ons to realize geocoding on small data size( <1,000 observations). Geocoding is pretty cool!
My python code reference is here:https://www.shanelynn.ie/batch-geocoding-in-python-with-google-geocoding-api/
