title: Changing font size of one cell in excel using C#
body: <p>I am working on a project that writes data to an Excel file. </p>
  
  <p>Everything is finished now, however I need a few cells with a bigger size than the rest (title, etc). </p>
  
  <p>I have read about this about the internet, but I keep having the same problem: when I execute my code (see below for what I have tried), everything in the worksheet becomes larger. </p>
  
  <p>What I already have tried:</p>
  
  <pre><code>worksheet.Rows[1].Cells[7].Style.Font.Size = 20; 
  
  worksheet.get_Range("A7", "A7").Style.Font.Size = 20;
  </code></pre>
  
  <p>None of this seems to work; what is the correct way to increase a cell's font size? </p>
