You can connect Google Forms and Sheets with the Twilio Lookup API to validate phone numbers and retrieve additional information, saving businesses time and effort in manual lookups. To do this, you need a free Twilio account, a Google account, and a Google Apps Script that integrates the two services. The script uses the Twilio Lookup API to validate phone numbers and populate additional columns with carrier, country code, and national format data. Once set up, the script triggers automatically when a form is submitted, enhancing the form's usefulness and power.
