Question: how do i create a formula in excel to say yes or no?
Answer: 1. Select the whole column by clicking at the column header, for instance, column A, and then click Data > Data Validation > Data Validation. 2. Then in the Data Validation dialog, under Setting tab, select Custom from the Allow drop down list, and type this formula =(OR(A1="Yes",A1="No")) into the Formula textbox.
