how to use data validation in excel

Using data verification in Excel is mainly to limit the data type or range of input in cells and prevent incorrect input. 1. Restrict input to specified options: By setting the source of the list (such as "male, female, unknown"), the drop-down menu selection input is realized; 2. Set the value range: For example, set the age between 18 and 60, select an integer and set the minimum maximum value; 3. Prevent duplicate content: Check uniqueness with the formula = COUNTIF(A:A,A1)=1 to avoid duplication of ID number and other repetitions; 4. Ignore blank items: Check "Ignore empty values", allowing blanks, but the rules must be compliant when filling in, such as 11-digit phone numbers. Using these functions rationally can greatly reduce input errors, especially suitable for multi-person collaboration scenarios.
