A simple use case; collaborating on a single excel file list of projects with multiple team members.

Hi all! I'm new to SS. I have a super simple use case. I've uploaded an excel file of a list of projects (not a project plan) that our team is collaborating on. Each member of the Team will update the information on the list, with each row representing a project assigned to them and each column representing project information (e.g., status, level of effort, milestone, week to week updates etc). The list is not a project plan but simply a list of all projects being worked on by our team. Can you please point me to some resources that can help build out functions for such a simple use case?
