In Salesforce formula editor there are two functions ISBLANK() and ISNULL(). What is the difference in both?

Hi Udit,

ISBLANK – If an expression has a value and returns true if it does not. If it contains a value, this function returns false. Text fields cannot be null. So use mainly for text fields.

ISNULL – If an expression is null (blank) and returns true if it is. If it contains a value, this function returns false. Numeric fields cannot be blank. So use mainly for numeric fields.
