title: How to keep first 0 in csv when open it and save as in Excel
body: <p>I created csv file in format "Surname;Birthday;Name". Where Birthday is in format ddmmyyyy (e.g. 01121989 or 09111983). </p>
  
  <p>When I opened it in Excel It did not show first '0'.</p>
  
  <ol>
  <li>Can I escape this symbol to show full date in Excel?</li>
  <li>When I saved this file from Excel using option "Save as" It lost first '0' in Birthday. Is it possible to prevent this? </li>
  </ol>
  
  <p>Thank you.</p>
