Hi,
Where is the datatable test coming from?
are you just declaring it or reading it from somewhere

Hi @vishal.kp
Just declaring it

So thats the error, You need to declare the data table with the number of columns that you are inserting, Or else you will get a null reference exception. Just use build data table with those number of column names.(before doing the add datarow) :slight_smile:

Thankyou.

one more query every time in a loop if I add datarow it will add to a new row?

WHile using for each row, If you want to input value to that column do -> row(“Columnname”)=“Value”

Hii

I have a if condition so if that is true then for each row starts where i have to update an excel say test but if the if condition is false also i have to enter the data in same excel test

so do I have to use 2 write range because if I use write range in for each then other condition is not satisfied…

Thanks and Regards,
