You can also create a checkbox toggle with Wingdings (o in Wingdings is a blank checkbox, x in Wingdings is a filled checkbox).
I made a video about how to do this, but if you just want the code, I have that below too. I used the Wingdings in Column C, just make sure to revise the code as needed.

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
' Specify the range where the checkboxes are located (column C)
If Not Intersect(Target, Me.Range("C:C")) Is Nothing Then
Cancel = True ' Prevents entering edit mode on double-click
' Check if the font is Wingdings and if it is a checkbox (either "o" or "x")
If Target.Font.Name = "Wingdings" Then
If Target.Value = "o" Then
' If the value is "o", change it to "x" (checked box)
Target.Value = "x"
ElseIf Target.Value = "x" Then
' If the value is "x", change it back to "o" (unchecked box)
Target.Value = "o"
End If
End If
End If
End Sub
