title: Access the "Locale" for Google Sheets
body: <p>How can I access the "Locale" set in <code>File &gt; Spreadsheet Settings &gt; Locale</code>?</p>
  
  <p><code>Session.getActiveUserLocale()</code> does not match the value chosen in <code>File &gt; Spreadsheet Settings &gt; Locale</code>. </p>
  
  <p><strong>- Extra Info -</strong></p>
  
  <p><strong>Reproduce:</strong> In Spreadsheet Settings, you can choose "Italy" for your Locale.  <code>Session.getActiveUserLocale()</code> will return "en" instead of "it".</p>
  
  <p><strong>My use case:</strong> I am trying to know when a function should be written with ";" or "," separating its parameters.  Google Sheets switches to ";" or "," automatically when <code>File &gt; Spreadsheet Settings &gt; Locale</code> is changed. So I want to know what property it is watching to make this change.</p>
