How to keep format of above cell to next other cells?

I am reading whole sheet data and saving it in one data table. In between activities writing again in same sheet some of the new data is adding. And the format of that newly added row is changing completely. How can we overcome that in this?
Highlighted in below screenshot. As “B” column is date and in “H” column formula is there which changing according to “B” column.

In Which format do you need?

I want format which is present in 509 row.

In Write cell you can give the format
CDate("the variable ").ToString(“dd-MMM-yyyy”)

till last row of that sheet i want same format. how to give range then? and that data is coming from other sheet were the format is like 510 row.
