Creating an Excel program with multiple tabs linked to a master tab is feasible, but it has limitations. Users can reference cells across tabs by starting a formula with an equals sign and selecting the desired cell, but this method does not allow for simultaneous data entry in both the master and individual tabs. If data is entered in one tab, it will overwrite the formula in the linked cell. For tracking employee activities, a more efficient solution may involve using database software, which can handle multiple entries and link them to a master record seamlessly. Alternatively, Microsoft Groove can facilitate collaboration by allowing all users to modify a shared document, automatically updating everyone's copy. For advanced users, Visual Basic for Applications (VBA) can be utilized to create a more dynamic linking system between tabs. However, using VBA requires adjusting security settings to allow macros to run, as they can pose security risks. Overall, while Excel can manage basic linking, it may not be the best tool for complex data management needs.
