Hey @Sathya123
Can you provide some conditions on which your validations will be like. The date entered is less than today's date. If the format is correct or not. For name, validation is a little difficult, for name validation can be first name and last name cannot be blank.
Below I am giving you some examples:
For name: First Name and Last Name are not blank.
Split Function: split(variables('A'),' ')

Then on dates you can check that it is less than today's date:

With conditions you can easily do that validation according to your need.
I hope this helps.
