title: Sum numbers in a string Google Sheets
body: <p>I need to sum all the numbers in a string, in the string there won't be any letters only numbers. The cell contains <code>112121</code>.</p>
  
  <p>I tried using <code>SUM</code> and <code>CASE</code> with the <code>QUERY</code> Function, but <code>CASE</code> is not supported.</p>
  
  <p>Example: <code>1121</code> = 5.</p>
