Format checks are procedures used to ensure that data is entered in a specific, predefined way. This can include verifying that dates are in the correct format, such as MM/DD/YYYY, or that email addresses contain the necessary components, like an '@' symbol. These checks help maintain data integrity and prevent errors in databases or software applications. By implementing format checks, organizations can reduce the risk of processing incorrect information. For example, if a user inputs a phone number without the required digits or symbols, the system can flag it for correction. This ensures that all data adheres to the expected standards, improving overall accuracy.
