Data Validation• Controls the type of data or the values input in a cell• Reduces input errors• Multiple criterion can be applied to a cell
CSE 2111 9-Data Validation and Macros
Display a message dialog box Restrict input to a whole number within limits
Restrict input to values in a drop down list Restrict input to a decimal number within limits
Restrict input to a certain time frame. (either date, time, or both)

Macro Example Scenario
You work for a company that employs people to make customer satisfaction calls for various companies. Your department provides services for all the major auto makers in the U.S. Each employee is assigned a state and it is their job to call each household and conduct a brief survey.
You receive a weekly list of customers from each auto company and it is your job to separate the list by state and distribute the list to your employees.
Your manager would like the customers stored in an Excel file with each state having its own worksheet.
