For example, you need to evaluate that if a cell is Blank, the blank value, otherwise return a value “Delivered”. Moreover, IF function also tests blank or not blank cells to control unexpected results while making comparisons in a logical_test argument or making calculations in TRUE/FALSE arguments because Excel interprets blank cell as zero, and not as an empty or blank cell.
