I am trying to join cells in a row if a value exists in a cell in that row.
The data has been imported from a .txt file and various sub headers are split along 2, 3 or 4
Not sure if this is exactly what you want but it will get you close:
Sub summary()
Dim sh1 As Worksheet, sh2 As Worksheet
Dim N As Long, i As Long, r1 As Range, r2 As Range
Dim z As Long
Dim arr() As Variant
z = 1
Set sh1 = ActiveSheet
With ActiveWorkbook
Set sh2 = .Worksheets.Add(After:=.Sheets(.Sheets.Count))
End With
With sh1
N = .Cells(Rows.Count, "A").End(xlUp).Row
For i = 1 To N
If .Cells(i, "A").Value Like "Summary*" Then
arr = .Range(.Cells(i, "A"), .Cells(i, "H")).Value
sh2.Cells(z, "A").Value = Join(arr, " ")
z = z + 1
End If
Next i
End With
End Sub
