Excel VB to change the value of a cell dependent upon the value of another

I originally posted this as an Excel formula request to see if there was a clever way round without vb, but I don't think it's possible. VBA seems my best bet.

I want to change the contents of a cell depending upon a comparison test, this basically what I am wanting to achieve

if a2=b3 then make j2=g3 otherwise do nothing.

I will actually have a series of these to check (see my attached file). This  spreadsheet details what I want to ultimately achieve, but just the above element of it would be a tremendous help

Please try this....
In the attached, click the button "Transform Data" on the sheet to run the code and see if this is what you were trying to achieve.

Sub TransformData()
Dim ws As Worksheet
Dim lr As Long, i As Long, n As Long, j As Long, sr As Long
Dim cell As Range
Dim x()
Application.ScreenUpdating = False
Set ws = Sheets("Personnel_Records")
lr = ws.Cells(Rows.Count, 1).End(xlUp).Row
On Error Resume Next
For Each cell In ws.Range("E:E").SpecialCells(xlCellTypeBlanks).Areas
   If cell.Rows.Count > n Then n = cell.Rows.Count
Next cell
On Error GoTo 0
If n = 0 Then Exit Sub
ReDim x(1 To 1, 1 To n * 2)
For i = 2 To lr
   If sr = 0 Then sr = i
   If ws.Cells(i, 5) = "" Then
      j = j + 1
      x(1, j) = ws.Cells(i, 6)
      j = j + 1
      x(1, j) = ws.Cells(i, 7).Value
   ElseIf j > 0 Then
      ws.Cells(sr, 9).Resize(1, UBound(x, 2)).Value = x
      j = 0
      sr = i
      Erase x
      ReDim x(1 To 1, 1 To n * 2)
      j = 0
      sr = i
      Erase x
      ReDim x(1 To 1, 1 To n * 2)
   End If
Next i
ws.Range("A1").CurrentRegion.Borders.Color = vbBlack
Application.ScreenUpdating = True
MsgBox "Task Completed.", vbInformation
End Sub

It is hard to understand your description on the sheet.
Would you please just populate the rows (after removing the comments from there) as per your logic and then explain the logic behind each row you populated on the sheet?
Steve KnightIT ConsultancyCommented:
Are you wanting this to happen as a user enters data into the sheet changing those cells or as one of run over it or button someone presses?

Cell checks or amendments are easy enough - I'm using phone at moment so bit looked at your sheet but can be as simple as

if range ("A1").value=range ("A2").value then range ("B1")=range ("A1").value

etc.  you could trigger the VBA when a specific cell or range of cells is changed or being run by button, sheet being saved or whatever us required.

Will look back when on Pc later.

Hi Subodh

I have attempted to illustrate a little better. I hope it makes sense. Thanks

Hi Steve

The data will be extracted from another source and pasted into the spreadsheet. The VB would then be executed to run through the spreadsheet and produce the desired results.

That's perfect thank you so much. You scored a hole in one.
