Formatting Data Sources from Folder

[ChrisFromOhio]

Hello - relatively new to Power BI, so I am hoping my question is an easy one. I have a folder of CSV data extracts, all in the exact same format, that I want to pull into Power BI. With each CSV extract, the first row is a row of selections I made when pulling the data. The second row is the row I want to use as data headers. In the first row is the date I want pulled and added as a custom column. The data currently looks like the example below:

Category=[ALL]	Subcategory=[ALL]	Brand=[ALL]	Viewing=[1/1/21 - 1/1/21]
Item	Item Description	Sales $	Sales U
354	Apple	10.25	4
640	Banana	3.75	2
887	Pear	11.32	5

And I would like to transform the data into the following (the bold row being the column headers)

Item	Item Description	Sales $	Sales U	Date
354	Apple	10.25	4	1/1/21
640	Banana	3.75	2	1/1/21
887	Pear	11.32	5	1/1/21

Hoping that making this change would apply to each CSV extract in the folder. Thanks for the help in advance!

@ChrisFromOhio I create a dummy pbix file using two csv files from my computer, see attached. and tweak it as you see fit.

@ChrisFromOhio you can create a custom function and then pass the content to the function, and that function will take the transformation, remove the first row and rest of the transformation.

@parry2k I've seen some of these posts, but my question pertains to adding a column based on the first row of data, then removing it and using the second column as my headers

[amitchandak]

@ChrisFromOhio , In power query, remove rows =1

then use the first row s header. Option under home menu

@amitchandak I know how to remove a row then make the next row a header, but before I remove the row I want to pull data from it into a column, then use the next row as the header.
