This is basically a program build to send advance birthday wishes to customers. Concepts Used: 1. The data of customers who have their birthday the day after tomorrow will be collected from an excel file containing the details of the customers. A sample excel file is also provided so that an idea can be provided about the format, while you can change the code according to your needs. 2. Browser automation is done using selenium through which we move along whatsappweb, the message conatining the birthday wish for the customer along with specifing his/her name will be sent automatically.(For example-> "Hi *Ritick Madaan* wish you a very *Happy Birthday* in advance, may your special day be full of happiness, fun and cheer!")
