Add a copy tab function, but remove all the formulas

In the desktop version of Excel on Windows/Mac, you can use a macro for this purpose:

Sub CopySheetValues()
    Dim ws As Worksheet
    Dim wt As Worksheet
    On Error GoTo ErrHandler
    Application.ScreenUpdating = False
    Set ws = ActiveSheet
    ws.Copy After:=ws
    Set wt = ws.Next
    With wt.UsedRange
        .Value = .Value
    End With
ExitHandler:
    Application.ScreenUpdating = True
    Exit Sub
ErrHandler:
    MsgBox Err.Description, vbExclamation
    Resume ExitHandler
End Sub

If you create this macro in your personal macro workbook (see here for more info), you can call it anywhere. For ease of use, you can create a keyboard shortcut and/or a Quick Access Toolbar button for the macro.
