Stop Bad Data from being entered into Excel using Data Validation Control

Excel has a feature called Data Validation that controls what the user can type into a cell. The entry choices include:

  • Any Value
  • Whole Number
  • Decimal
  • List
  • Date
  • Time
  • Text Length
  • Custom

Access Data Validation from the Data Tab.

Excel Data Validation

Select the cells you want to control then click Data Validation. Change the settings for what you want to allow. In this example I will choose List since I want to control user input to a list of categories for the expense report. I will enter “Auto Rental, Airfare, Lodging, Meals, Parking, Tips” in the source line.

Data Validation List

Click the Error Alert tab and write a message for the user to see after they enter bad data.
