Hi Community,
Currently i am trying to vlookup from multiple source of data and performing some calculation on the data. Below is the screenshot that i facing the issue. I knew how to vlookup from another single source by using join tools. May i know how can i build the workflow if i have so many data file to vlookup with? Could anyone guide me on this or share the samples of workflow? I also attached the file below for your reference.

Many thanks in advance.
