geocode-csv: Geocode a CSV file using the SmartyStreets API

(This project is not associated with SmartyStreets.)

WARNING: This project geocodes CSV files thousands of rows per second, which can use up your SmartyStreets quota very quickly. This may cost you money.

If you have a CSV file that appears as follows:

name,street1,street2,city,state,zip
Resident,1600 Pennsylvania Avenue NW,,Washington DC,20500

...and an address_spec.json file that appears as follows:

{
    "geocoded": {
        "street": ["street1", "street2"],
        "city": "city",
        "state": "state",
        "zipcode": "zip"
    }
}

...then you can geocode it using:

# Set up credentials.
export SMARTYSTREETS_AUTH_ID=...
export SMARTYSTREETS_AUTH_TOKEN=...

# Geocode the CSV.
geocode-csv --spec address_spec.json < in.csv > out.csv

This will add a series of columns starting with geocoded_, which will contain various postal delivery information, plus estimated latitude and longitude. If geocoding succeeds, geocode-csv will return 0. If it fails, it will return a non-zero error code and print a human-readable error message to standard error.

You can geocode multiple addresses per row as follows:

{
    "geocoded_shipping": { /* ... */ },
    "geocoded_billing": { /* ... */ }
}

This will insert two sets of columns, one beginning with geocoded_shipping_ and the other with geocoded_billing_.
