Parameters enable users to interact dynamically with the data in the workbook. Users can select or input values, and the workbook updates its content accordingly. This enhances user engagement and allows for more flexible data exploration. By using parameters, you can create variables to store values that can be reused across different parts of the workbook. This makes it easier to maintain and update the workbook, as changes to the parameter automatically propagate to all parts where it's used.
