Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    If Target.Column = 1 Then
        If Target.Row = 3 Or Target.Row = 5 Then
            Beep
            Cells(Target.Row, Target.Column).Offset(0, 1).Select

Is there a way for this VBA code to run automatically every time someone opens the file?

  Hi Aaron,
  After adding the code, please save the workbook as an Excel Macro-Enabled Workbook (click File > Save As > specify a folder for the file > choose Excel Macro-Enabled Workbook from the Save as type drop-down list > Save). After that, every time when you open the file, the code works automatically.

Hi,

I have tried to use the code for ranges you have previously posted but it isn't working - can you advise me if I should be combining the code for ranges above or below?

Thanks

Hello,

I used the code provided to Carlos and it did exactly what I wanted it to. Is there a way to have some ranges offset within the ROW to the right of the protected range (as the "Carlos" code already does), but have other ranges offset within the COLUMN to the cell directly below the protected range? I tried entering the "Carlos" code twice and changing the offset, but I received a variety of errors.

Thank you

Is there any function to set for example Row 2 cell 13 to 900? Or do i need to manually punch each cell name in the code?

Dear Crystal,

Thank you so much for this! It works perfectly.

I have used the code in Carlos' comment to run the macro automatically as you open the file. I was wondering if there is a way of having an "Undo" button or something like it, that allows you to cancel that code and therefore, unlock those ranges that have been locked.

I want those to be locked most of the time, but I would like to unlock them should I need to change any of the data. The only reason I am not protecting the whole sheet is because, if I do, it deactivates the ability to expand on tables. That in turn, expand on a line chart.

Thanks so much for the help!

  Hi Erin,
  You can manually break the code by clicking the Break button in the Microsoft Visual Basic for Applications window to unlock those ranges. And run the code to activate it again. Thanks for your comment.

Dear Crystal,

Is there anyway that this macro can be run automatically upon opening the file, or upon clicking any cell. I don't want people to have to run the macro manually in order for the required ranges to be protected.

Also, I will need to protect 12 non adjacent ranges. For example: I11:I20 and K11:K20 and M11:20 etc... How do I do this?

Last, and this one might be asking too much, but is it possible to apply the protection to the example ranges that I provided above, BUT then extend the protection down additional rows as new ones are added? In other words, protection would be applied to I11:I20 and K11:K20 and M11:20, but a user would be able to add a new row (row 21), with new data, but once the new row is added, then the protection would apply to I11:I21 and K11:K21 and M11:21. Am I asking for the moon? :-)

Thank you for everything that you've already provided! I can't thank you and other people like you enough for sharing the your knowledge. Amazing!

  Dear Carlos,
  The following VBA code can help you solving the problem. Please fill in your ranges in the fourth line of the code and press the Alt + Q keys to return to the worksheet. Then please shift to other worksheet and then go back to current sheet to activate the code. Thank you for your comment.
  
  Dim xRg As Range
  Private Sub Worksheet_Activate()
  If xRg Is Nothing Then
  Set xRg = Union(Range("I10:I20"), Range("K10:K20"), Range("M10:M20"), Range("O10:O20"))
  End If
  End Sub
  Private Sub Worksheet_Change(ByVal Target As Range)
  Dim I As Integer
  Dim xRgNew As Range
  Dim xRgLCell As Range
  On Error Resume Next
  Application.EnableEvents = False
  For I = 1 To xRg.Areas.Count
  Set xRgLCell = xRg.Areas.Item(I)
  Set xRgLCell = xRgLCell(xRgLCell.Count).Offset(1, 0)
  If Target.Address = xRgLCell.Address Then
  If xRgNew Is Nothing Then
  Set xRgNew = Target
  Else
  Set xRgNew = Union(xRgNew, Target)
  End If
  End If
  Next
  Set xRg = Union(xRg, xRgNew)
  Application.EnableEvents = True
  End Sub
  Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  On Error GoTo Exitsub
  If (Not Intersect(xRg, Target) Is Nothing) And (Target.Count = 1) Then
  Target.Offset(0, 1).Select
  End If
  Exitsub:
  End Sub

Dear Crystal,

You have provided me with a solution (half of it) that I have been struggling for the last few weeks, but I would need some more hints.

How this could be applied to a table range only, not whole worksheet? Thanks in advance.

  Good Day,
  As the VBA code provided below, please change the specified range "H:J,4:46" to the table range you only want to lock in the worksheet.
  And cells(1,1) should be the cell outside the table range. When clicking on any cell in the table range, the cursor will be moved to that cell automatically.
  
  Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  Dim xRg As Range
  Dim xRgEx As Range
  Dim xRgExEach As Range
  On Error Resume Next
  Application.ScreenUpdating = False
  Set xRg = Range("H:J,4:46") 'Change the row range and column range you will lock without protecting worksheet
  Set xRgEx = Application.Intersect(xRg, Target)
  If xRgEx Is Nothing Then Exit Sub
  Cells(1, 1).Select 'Specify a cell you will shift to after selecting the locked cells
  Application.ScreenUpdating = True
  End Sub

  Dear AJ,
  If you want to lock a range of specified rows and columns, please try the below VBA script.
  
  Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  Dim xRg As Range
  Dim xRgEx As Range
  Dim xRgExEach As Range
  On Error Resume Next
  Application.ScreenUpdating = False
  Set xRg = Range("H:J,4:46") 'Change the row range and column range you will lock without protecting worksheet
  Set xRgEx = Application.Intersect(xRg, Target)
  If xRgEx Is Nothing Then Exit Sub
  Cells(1, 1).Select 'Specify a cell you will shift to after selecting the locked cells
  Application.ScreenUpdating = True
  End Sub

  This is a great workaround, especially in shared workbooks where turning protection on/off is unsupported. Thank you so much.

I wanted to hide formula in Cell O1. Please inform formula for the same.

  Dear ajay,
  If you want to hide formula in cell O1 without protecting the worksheet, please try the below VBA script.
  Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  Static TheFormula As String
  If Target.Address = "$O$1" Then
  With Target
  TheFormula = .Formula
  .Value = .Value
  End With
  Else
  With Range("O1")
  If Not .HasFormula Then
  .Formula = TheFormula
  End If
  End With
  End If
  End Sub
  
  After using the code, it seems that the formula of cell O1 is changed to formula result. Actually, it hides the formula with displaying the formula result in the Formula Bar. And the formula will display if the code is broken.
