 * When I try to edit/insert a new row that has a column with value “<“, it become
   a null value
 * For example, I have a column “Operator”, when I save “>=” as string, it is fine.
   
   When I input the value “<=”, it saved as null.

 * Hi,
 * We sincerely apologize for the late reply.
 * Could You please explain to us what You’re trying to do in a bit more detail?
   Did You set conditional formatting for “Operator” column, and when You’re adding
   new values it doesn’t show the “<=” value, but instead shows “0”; or are You 
   trying to add that rule in-line?
 * Thank You for Your understanding.
