title: Google Sheets: remove specific characters from string except decimal
body: <p>Hi I have a column of messy data within Google Sheets I'm trying to clean up and remove any non-numeric characters except decimals.</p>
  
  <p>I'm having issues with the expression syntax within REGEXREPLACE (this works to remove the brackets/ quotes/ colon but also removes decimals, I want the decimals to remain):</p>
  
  <p>=REGEXREPLACE(A1,"\D+", ""))</p>
