title: Regex for array in Google Sheets
body: <p>How do I remove non-numerical characters from a filter in Google Sheets?</p>
  
  <p>I have a function that spits out matching phone numbers into up to 3 subsequent columns. I would like to eliminate non-number characters and a prevailing 1 if there is one, possibly using Regex.</p>
  
  <pre><code>=array_constrain(transpose(filter(People!H:H,People!B:B=A10)),1,3)
  </code></pre>
