One way, assuming you mean you have

data
blank
data
blank

or something like that and you want the cell with data to fill in the blanks
below them?

Select the whole range, press F5, select special and blanks,
type equal sign, click on the first cell with data in the selected range,
press ctrl + enter
This will put a formula in the blanks cell refering to the cells above them,
if you want to remove the formula just copy and paste special as values in
place
