Error while combining different excel files

I want to upload excel files from a folder. All the files are in the below format.

And I want the result in "PowerBI-Query editor" as below :

But when I tried to combine and load the files using “Get Data”, datasource as a folder, I get the error either one of the files. I am not able to combine both the excel files either using “Unpivot Columns” or “Transpose”.

Any solution regarding the above issue ?

Thanks
