Send an SMS Message From an Excel Spreadsheet

This blog post demonstrates how to use Microsoft Excel's Visual Basic for Applications (VBA) to send SMS messages using the Vonage SMS API. The process involves creating a spreadsheet with the cell phone numbers and text to be sent, enabling developer mode in Excel, adding a reference to the Microsoft XML 6.0 library, and writing VBA code to authenticate with the Vonage API and send the SMS message. The code is then assigned to a button for easy activation. Once set up, users can test the functionality by running the code and sending an SMS message to their specified phone number.
