validate Var_4 expect spec_char_count=1	NY 10011, USA	True
validate Var_4 expect space_count<=1	United States Of America	False
validate Var_4 expect frequency=1	India	True

5. List Rule

Example: Column: Country Requirement: Country should be either USA, Canada, or UK.

validate Var_6 expect not is_null	12345	True
validate Var_6 expect not is_null	(Empty)	(Empty)
validate if(Var_6 is null, true, false) expect is_true	__null__	True

7. Custom Condition Rule

Example: Column: Salary Requirement: If the job title is "Manager", the salary should be greater than 50,000.

• Input Variables: Var_7 (mapped to column JobTitle), Var_8 (mapped to column Salary)
• Expression: validate case when Var_7 == 'Manager' then Var_8> 5000 else false end expect is_true

Job Title	Salary	Expected Result
Manager	60000	True
Developer	45000	True (Not applicable)
