Lock cell without protecting worksheet

Priyal835 

Assume checkbox means an Activex control.

Private Sub Worksheet_Change(ByVal Target As Range)
Dim Condition As Byte
 If Target.Text <> "" Then Condition = 1
        If Not Intersect(Target, Range("$A$7:$H$7")) Is Nothing Then
        ActiveSheet.Shapes("Check Box 1").ControlFormat.Value = Condition  'Check box
     End If
    If Not Intersect(Target, Range("$F$8:$I$8")) Is Nothing Then
        ActiveSheet.Shapes("Check Box 2").ControlFormat.Value = Condition  'Check box
    End If
    If Not Intersect(Target, Range("$F$9:$G$9")) Is Nothing Then
        ActiveSheet.Shapes("Check Box 3").ControlFormat.Value = Condition  'Check box
    End If
  End Sub

If it's not an Aktice X control, it won't work, after all, these controls are there to make specific entries in protected spreadsheets despite protection.

Otherwise it would not be possible to create any meaningful applications that users without Excel knowledge could use without hesitation :).

Important to remember: The words "protect" and "protected" have a general meaning, but Microsoft, in the context of Excel, has a specific meaning when referring to protecting (technical sense) a worksheet.  It may be easy to confuse the two.

<< I don't want to protect the entire worksheet. I only want to lock the formula in specific cells... >>

I'm certainly no expert on the protection (general sense or technical sense) of worksheets and cells.  But it does not help that Excel terminology is misleading: using a "Locked" property to indicate the equivalent of having a physical lock installed, and "protect the worksheet" as the equivalent of locking all the existing physical locks (among other changes in behavior).  Let me emphasize this: Protecting a worksheet (Excel technical sense for changing one property of a worksheet that affects the ability of users/software to change its contents, change the visibility of rows and columns, and other things) may cause all of its cells to be protected (general sense) from a change of content (and that's the default) ... or it may cause only some of the cells to be protected (general sense) from a change of content (if only some of the cells have a format of Locked).

So regarding << The software they are running won't work with the worksheet protected >>, I have to wonder how many of these are true (multiple choice):

1. The software won't work when the worksheet is protected and all of the cells are locked.
2. The software won't work when the worksheet is protected and some of the cells (those which are directly used by the software) are locked.
3. The software won't work when the worksheet is protected and some of the cells (none of which are directly used by the software) are locked.
4. The software won't work when the worksheet is protected and none of the cells are locked.

I can readily believe that #1 and #2 are true, but the others ...?  And even for #1 and #2, there may be workarounds, such as changing the worksheet protection and or cell locking at times via VBA.

<< Every explanation given in this thread shows protecting worksheet as the last step >>

No.  Reread the 17 May 2021 post by Hans.  The only use of "protect" in his post is in the general sense.

I understand your situation if you are not willing or not allowed to use VBA in your relevant workbooks.  But if you are not limited that way, you have two options for protecting (general sense) your formulas.
