combine multiple excel files have different header into one

Hi,

 

I have multiple excel files which is in SharePoint online folder which looks like below table.

  

 Excel File 1
 01/01/201802/01/201830/01/201831/01/2018
Asia    
EU    
US    

 

 Excel File 2
 01/02/201802/02/201827/02/201828/02/2018
Asia    
EU    
US    

 

Each of the file has a "date" as a table header, it is not fixed because of number of date in that month (28 to 31 days),

I'd like to combine all data by paste it next to each other (vertically) to be unpivot, is there any methods to combine it in Power Query?

 

I think creating 1 query per file, and unpivot, then append (or merge) query is mostly simple, but I'd like to automize the job for coming months because I have multiple partners and all of them has same structure of the tables, need to be refresh my dashboard daily basis so it is hard to make it one by one every day.

 

Current "combine files" feature only support adding data below down, it was very hard to rearrange the data for me.

 

Thanks and regards,

Hanwool

Instead of creating multiple queries and append subsequently, it would be easiest to store all your files in one folder and then use the Import from folder method. But instead of using Binary combine, write your own custom function that unpivots first, before combining all results from the different sources.

Check these sources on how to write your own function:
