hi please help me

Hi Amit Verma

Welcome to the forum

I would love to try to help, but do not have a clue about what you want.

It will probably help others to help if you were to describe what you are trying to do and post an example of what you have (all sensitive data removed) and an example of what you are trying to achieve.
