Selecting all Unlocked Cells
As you probably know, when a worksheet is protected, only the unlocked cells can be changed. You may want to apply different formatting to the unlocked cells, or simply ensure that the correct cells are indeed unlocked.
Oddly, there is no direct way to quickly identify which cells are locked or unlocked. When the sheet is protected, you can use the Tab key to move among the unlocked cells, but it you would like to select them all you'll need a macro.
The macro listed below selects all unlocked cells on the active worksheet.
Sub SelectUnlockedCells()
Dim WorkRange As Range
Dim FoundCells As Range
Dim Cell As Range
Set WorkRange = ActiveSheet.UsedRange
For Each Cell In WorkRange
If Cell.Locked = False Then
If FoundCells Is Nothing Then
Set FoundCells = Cell
Else
Set FoundCells = Union(FoundCells, Cell)
End If
End If
Next Cell
If FoundCells Is Nothing Then
MsgBox "All cells are locked."
Else
FoundCells.Select
End If
End Sub
