title: How load a specific sheet from a Spreadsheet
body: <p>I have a Spreadsheet that contains a lot of sheets, and I need to load one of these sheets, how can I do that?</p>
  <p>Here is a photo of the sheets in my Spreadsheet
  <img src="https://i.stack.imgur.com/atgwz.png" alt="sheets" /></p>
  <p>Here is my idea how to do it:</p>
  <pre><code>var sheet = SpreadsheetApp.openById(index).getSheetByName('Geração de Demanda');
  </code></pre>
  <p>Should that be working?</p>
