Fill non-contiguous blank cells with the value from the cell above the first blank

• Select A1:A8.
• Press F5 to show the Goto dialog.
• Click Special ….. Select Blanks and click OK.

That will select a noncontiguous range of blank cells.

• Then, without selecting anything else, type =A3 and press control+enter.
• That will enter an array formula in all the blank cells referring to the cell above it.
• Reselect A1:A8, and Edit – Copy.
• Then Edit – Paste Special – Values. And you’re all set.

Note that the =A3 refers to the cell above the first blank cell.

If you want to do it with a macro, you could loop through the cells and fill in the empty ones.
