Validate addresses using Google Maps Address Validation and Apps Script. Discover onleeaddress the add-on for Google Workspace.
I missed the announcement in November 2022 that there is a new Google Maps Address Validation API. I also missed this post from Stéphane Giron showing how you can use the Address Validation API in Google Apps Script.
The concept is simple, you provide the Address Validation API with what you think is a correct address and the API returns information on each component of the address and additional metadata. Visit the source post for more details on setup and some example code.
