Filling all the empty cells between two equal cells in same column in excel sheet (with the same value of the equal cells ) - excel

Question

I have the following excel
I am trying the following code
> Sub fill_blanks()
Dim i As Long
i = 2 '
Do Until Range("B" & i) = ""
Range("B" & i).Select
If ActiveCell.FormulaR1C1 <> "" Then
Range("A" & i).Select
If ActiveCell.FormulaR1C1 = "" Then
Range("A" & i - 1).Copy
Range("A" & i).PasteSpecial Paste:=xlPasteValues
Else
i = i + 1
End If
Else
i = i + 1
End If
Loop
End Sub >
What I need to check is if the cell is not empty, then to keep its value, and if it was empty to check the first next not empty cell and the previous non empty cell in the same column, and if they have the same value, then to fill all the empty cells between with the same value, and if the two cells are not matching, then to return X.
So the result will be as following
But using the code , I am getting something different.
This what I get with this code

Answer 1

Find the last used row LastRow so we know where to stop.
Loop through your rows, when you come accross an epmty cell remember it FirstEmptyRow
Keep looping until you find data again, the row before is then LastEpmtyRow. Now we know the beginning and the end of the empty space.
Check if above the epmty space and below the empty space is the same date. If so fill it into the empty space otherwise fill in x.
So you end up with something like
Option Explicit
Public Sub FillData()
Const START_ROW As Long = 2 'define first data row
Const COL As String = "A" 'define the column
Dim ws As Worksheet 'define your worksheet
Set ws = ThisWorkbook.Worksheets("Sheet1")
Dim LastRow As Long 'find last used row in column A
LastRow = ws.Cells(ws.Rows.Count, COL).End(xlUp).Row
Dim FirstEmptyRow As Long, LastEpmtyRow As Long 'first and last empty row of a empty range
Dim iRow As Long
For iRow = START_ROW To LastRow
If ws.Cells(iRow, COL).Value = vbNullString And FirstEmptyRow = 0 Then
'found first row of an empty range
FirstEmptyRow = iRow
ElseIf ws.Cells(iRow, COL).Value <> vbNullString And FirstEmptyRow <> 0 Then
'found last row of an empty range
LastEpmtyRow = iRow - 1
'check if same date to fill either the date or x
If ws.Cells(FirstEmptyRow - 1, COL).Value = ws.Cells(LastEpmtyRow + 1, COL).Value Then
'fill date
ws.Range(ws.Cells(FirstEmptyRow, COL), ws.Cells(LastEpmtyRow, COL)).Value = ws.Cells(FirstEmptyRow - 1, COL).Value
Else
'fill x
ws.Range(ws.Cells(FirstEmptyRow, COL), ws.Cells(LastEpmtyRow, COL)).Value = "x"
End If
'reset variables
FirstEmptyRow = 0
LastEpmtyRow = 0
End If
Next iRow
End Sub
