title: Excel VBA: How to disable external references to a veryhidden tab?
body: <p>I have a pw-protected Excel file to send to an end-user. There are veryhidden tabs in the workbook.</p>
  
  <p>I want to prevent said end-user from just opening a new workbook, creating a cell reference to one of the veryhidden tabs assuming they can guess those tab names (generic names (e.g. "Inputs")) and recreating the file from there. </p>
  
  <p>Is there a way to do this in VBA?</p>
