Hi @Kyle - this is actually pretty simple to do with Make (formerly Integromat).
You set up a suitable trigger for your “Scenario” (Search, Updated or New Record etc) and then use the Google Maps module to calculate the distance for you. You can then update the same record with the result:
You needs a Google Maps API account to do this - which is fairly straightforward to set up and then connect your Make module to that.
The advantage is that this is still a NO CODE solution!
