Excel vba - How to copy/paste when range varies - excel

Question

Got a sheet holding 7000 rows. Data is in columns A-C. Column A is teams, B is persons, and C is towns. Row 1 holds headers.
Cell A2 is the first team name. Cell B2: C23 is persons and towns (no empty cells). However, cell A3: A23 is empty. The team name is only written out for the first row of persons/towns.
Row 24 is blank.
In A25 there is a new team name. B25:C38 is persons/towns. A26: A38 is empty.
What I want to do is to copy/paste team name in A2 down to empty cells in A3: A23. And then do the same with the team name in A25 to A26: A38. And so on down about 7000 rows for 370 teams.
But the number of rows in use for each team varies, so how can a VBA take this into account?
The only fixed information is that there is an empty row between each team/person/town-section.

Answer 1

I came up with a quick solution that takes into account blank lines:
Option Explicit
Sub completeTeams()
Dim i As Long
Const startDataRow = 2
Dim lastDataRow As Long
Dim lastTeamRow As Long
Dim lastTeamFound As String
Dim teamCellData As String
Dim isEmptyLine As Boolean
Rem getting the last row with data (so using column B or C)
lastDataRow = ActiveSheet.Cells(ActiveSheet.Rows.Count, "B").End(xlUp).Row
teamCellData = vbNullString
lastTeamFound = ActiveSheet.Cells(startDataRow, "A").Text
For i = startDataRow To lastDataRow
Rem trying to get the actual team name
teamCellData = ActiveSheet.Cells(i, "A").Text
Rem check to skip empty lines
isEmptyLine = Len(teamCellData) = 0 And Len(ActiveSheet.Cells(i, "B").Text) = 0
If isEmptyLine Then GoTo skipBlankLine
If Len(teamCellData) > 0 Then
lastTeamFound = teamCellData
End If
ActiveSheet.Cells(i, "A").Value = lastTeamFound
skipBlankLine:
Next
End Sub

Answer 2

If you're ok with a formula only approach you could add this formula to cell D2 and copy down.
=IF(B2<>"",IF(A2="",D1,A2),"")
Then copy column D and paste values into column A.

Answer 3

Actually wrote such a script myselft a few years ago, since a lot of analytics toolds exports information to excel like that
Select the range you want to work on, i.e A1:A7000, and run the script:
Sub fill2()
Dim cell As Object
For Each cell In Selection
If cell = "" Then cell = cell.OffSet(-1, 0)
Next cell
End Sub
