Get Data

Get Data:
MS-Excel 2016 includes a powerful new set of features called Get Data, which provides fast, easy data gathering and shaping capabilities. Get Data enables you to connect, combine, and refine data sources to meet your analysis needs. While some data analysis efforts focus on a few of these steps, each step is important in the data analysis and transformation process.

Data Validation:
In MS-Excel 2016, data validation is a feature that is used to control what a user can enter into a cell. For example, you could use data validation to make sure a value is a number between 0 and 8, make sure a date occurs in the next 30 days, or make sure a text entry is less than 20 characters.
 
Data validation can simply display a message to a user telling them what is allowed. Data validation can also stop invalid user input. For example, if a product code fails validation, you can display a message like what you want to say. In addition, data validation can be used to present the user with a predefined choice in a dropdown menu. This can be a convenient way to give a user exactly the values that meet requirements. And data validation is implemented via rules defined in Excel's user interface on the Data tab of the ribbon.
