Thanks for the creative contribution! Excel import is a cool feature, but it introduces complexity that goes beyond this tutorial's scope. This repo is designed to teach basic MERN CRUD so learners can understand the full flow from React form to an Express route to a MongoDB document. Adding Excel parsing and bulk inserts would make it harder for beginners to follow the fundamentals. That said, Excel import is a great feature to add to your own fork! Closing as out of scope.
