title: Google Sheets Regular Expression String before a dot
body: <p>I have a string &quot;öioajsdflöjskadf.cfg&quot; where I would like to extract &quot;öioajsdflöjskadf&quot;.</p>
  <p>I know the formula REGEXTRACT gets me there. I just struggle finding the correct regular expression.</p>
  <p>To be more precise: I want to extract everything before the &quot;.&quot;</p>
  <p>Can anyone help?</p>
  <p>Best,
  Florian</p>
