TwilioSheet is an application that allows users to receive SMS messages in a Google Spreadsheet, making it easy for developers and non-developers alike to process and act on incoming messages. The application was created as a result of a collaboration between the author and Jason Laveglia, who wanted to use Twilio to set up a marketing campaign that allowed people to sign up for updates by texting a keyword and email address. After realizing that using a Google Spreadsheet was a viable solution, TwilioSheet was born, offering a simple way to collect SMS data without requiring any coding knowledge. The application can be used for various use cases, such as keyword marketing campaigns, contact forms, expense tracking, time tracking, and polling/voting applications.
