Dashboards: Dashboard is a visual display of the data and these are dynamic and live, so data is being updated in real-time and visuals can show changes from minute to minute.
Reports: Reports are not live and we use historical data to make reports. sometimes Reports are included with visuals such as Table, Graphs and Charts, Text, Numbers or anything.
Structured references – Instead of using cell references, we can use an Excel table name or the Column name for reference.
