How to write excel cell from Data Table without missing Zero as prefix

I Am trying to filter the Excel file and saved that filtered data into files. but while creating seperate files some column data from main file which starts with Zero (0) missed to update as it is and skips Zero.
Can anyone please help to fix this. I have tried so many different activites postd in Forum but no luck.

I have attached my code and Excel file for more reference. (40.0 KB)
