title: string (123) in Excel csv file
body: <p>I am creating csv file for importing into Excel. Some values are strings (123). </p>
  
  <p>I need them to show as (123). Excel shows them as -123. </p>
  
  <p>Which characters can I add to (123) to make Excel show them as (123), without any need for post-import manual formatting ? </p>
  
  <p>Tried double-quotes, did not help. Thanks.</p>
