Regular Expression

Regular Expression Usage

Regular expression can be used in column validation to validate and restrict user input. Eg. matching emails from specific domains, matching numbers within a specific range, matching a word or a phrase in a list etc...

Your regex should start with ^ and end with $ and match the whole input if it's valid.
