Hi Ivan,

Can you please elaborate little more on the join condition that you are using ?
is it like the below one?

If it is an inner join you dont have data that matches both the join condition, that may be the reason for not finding any data on the DT3. Please correct me on your join condition I would be able to help you out.

Thanks

Hello friend, I did just that same condition as you mentioned and indeed my DT3 does not bring me anything even if the columns have the same name

Problem is that condition doesn’t satisfy any data in the final result. As the values in EXcel 2 are in lower case compared to values in Excel1 so inner joins may not find any result. If you change the data to be upper case you will get some inner join results.

I will try to change everything to uppercase
