Excel公式，如果旁边的单元格已经为空，则将单元格转换为空单元格

Question

I need a formula in excel that turns the cells in column D empty if the corresponding cell in column C (ie on the same row) is already empty.

To elaborate, this is a sample from my excel sheet:

   C     D
1  0,5   500
2  0.3   400
3        600
4        700
5  3.1   400
6        350
7  1.1   400

I want it to turn into this:

   C     D
1  0,5   500
2  0.3   400
3        
4        
5  3.1   400
6        
7  1.1   400

All the values are hard coded. Is what I want possible?

Answer 1

Not sure what you have in D1 to already create value etc.

But try:

=IF(C1="","", Your original value/formula here )

Answer 2

Pretty sure you can't use a formula in this case. What you need is a macro

Sub EmptyCells()
    For Counter = 1 To 20
        Set cell = Worksheets("Sheet1").Cells(Counter, 2)
        If IsEmpty(cell.Value) = True Then
            Worksheets("Sheet1").Cells(Counter, 3).Value = ""
        End If
    Next
End Sub

You can call the vba editor with alt+F11. Right click your sheet and select Insert->Module. Paste the code in there and save the excel as .xlsm file. Open the macro view with alt+F8 and run your macro.

After you run the macro all values from column D that have an empty Value in column C will be empty too.
