hi bro
one more issue.
after open this 2 files, i want to merge them into 1
they have same columns
so, i will turn them into collection first, right? but the thing is that we have just gone through the loop, and the data item is only 1
how we can turn into 2 collections then ??? (because we will need 2 data items right ? but the loop above generated only 1 data item)
