@Rudrabhadra Use CHAR(10) every time you want to enter a line break and don't forget to set the cells to wrap text.
If you use CONCAT or CONCATENATE, that may be quite some typing as you have to include CHAR(10) between all text arguments. To make it bit easier, you could type the formula =CHA(10) in a cell. Give it a name, e.g. lb (small L, small B) and then use that. Something like =CONCAT(D1,lb,E1,lb,F1,lb, etc...)
Or if you have MS365 or Excel 2021, use TEXTJOIN and use CHAR(10) as the delimiter. that could look like this:
