i've been trying to combine 2 excel files with same template (no header row). Unique identifier is in the first column. I'm trying to use power query but show no progress. Here's the data data1 data2
I expect output such as output1 output2
I've been trying with power query and it results duplicate values with null data in other columns Power Query Result
Any idea how to merge it? I'm trying to merge other files but i'm using simple one to use the fundamental.
Please kindly advise.
Thanks
