title: Excel formula to SUM all numbers in a cell with text
body: <p>I have cells in my spreadsheet who are like:</p>
  <pre><code>RF(4);MN(4);LL(2);TE(4);HA(2)
  </code></pre>
  <p>There is a formula where I can sum all the numbers in that String/Cell?</p>
  <p>I can try another way by Office Script, but since he has low speed, and I have to sum a lot of lines of cells with those type of string, i would try to accelerate the process with Excel Formula as much as possible.</p>
  <p>best regards</p>
