title: Excel formula to show linked cell ID
body: <p>In an excel cell, I've placed a simple formula</p>
  
  <pre><code>=C4
  </code></pre>
  
  <p>The cell typically displays the <strong>value</strong> of cell C4, but instead I want to see the linked cell <strong>ID</strong> instead, which in this case is "C4".</p>
  
  <p>Is there a formula to show me this? like:</p>
  
  <pre><code>=SHOWCELL(C4)
  </code></pre>
  
  <p>The reason I need this instead of simply typing the value of "C4" into the cell, is so Excel will <strong>maintain</strong> the link to the correct cell even if rows are inserted/deleted, AND show me which cell is linked.</p>
