Additional Excel Features: 1. DATA VALIDATION: Data Validation restricts the type of data or the values that users enter into a cell. So for instance, with Data Validation you can limit inputs in a given cell to a specific type of value (e.g. whole numbers only). You can also restrict inputs to only predetermined values (e.g. a drop-down menu with a specific list). 2. CONDITIONAL FORMATTING: Conditional Formatting allows you to create a custom look for certain cells (or the entire model) based on user inputs. 3. DATA TABLE: The Data table feature is a feature in Excel that calculates multiple results (i.e. outputs) instantly. This feature is especially useful for scenario analysis in real estate, as well as displaying outputs in a dynamic way. 4. CHARTING TOOL: Charting tools allows you to visually present your outputs in a compelling (and dynamic) way
