You can bring the power of Google Maps to your Google Sheets using simple formulas with no coding. You don’t need to sign-up for the Google Maps API and all results from Google Maps are cached in the sheet so you are unlikely to hit any quota limits.

The post includes all the source code and has some great examples using the V8 syntax.
