title: Linking a whole worksheet to another in Excel
body: <p>I have two workbooks that have sheets that logically should look identical. I don't want to manually maintain their identical-ness, so I want to dynamically link them (just as you'd do between cells using formulas: "=A1"). I want to link the <em>whole</em> spreadsheet, not just a few cells. </p>
  
  <p>Is there a way to do this without making 238427398729 formulas, thus crashing my machine? Is there a way to say "=sheet2" as a formula defining the content of a <em>whole</em> sheet?</p>
