title: Excel (via web) SheetName as cell value
body: <p>I have a formula that grabs the name of the sheet and stores it in the cell.</p>
  
  <pre><code>=MID(CELL("filename",A2),FIND("]",CELL("filename",A2))+1,255)
  </code></pre>
  
  <p>I use this as a header for different columns and charts throughout the workbook. I "shared" my workbook to OneDrive, which allows other users to access the workbook via web. The formula breaks when viewing via web. I have a feeling it is due to the self-referencing "filename" parameter. Anyone know a good workaround?</p>
