title: Truncate "Multiple lines of text" column in Sharepoint Online list
body: <p>I'm stuck on a particular scenario right now because of a recent change by Microsoft in Office 365 regarding the "Multiple lines of text" column in a Sharepoint list.</p>
  
  <p>My main goal is to truncate this column. If this column will have a lot of characters in it, it'll eat up the display page because it can have up to 60k characters. </p>
  
  <p>I'm looking to limit the rows of this column on the list page into like 5rows only  and then add a see more button if possible?</p>
  
  <p>I've found this article about formatting a column in sharepoint list using JSON.

  <p>I've seen that you can put the column into a div using this script but I'm just wondering if I'll be able to limit the rows of this column using JSON?</p>
