Thank you Tobias,

I searched google for a solution and found this website.

and i found that i could just merge the files using my terminal/cmd and removing all headers, I can manually add it again or use the code.

Thank you.

Yes, I indeed did that and that does work but i use my Mac terminal to merge the files and i use the header
“code” “product” “Day” “Week”
So if i merge 10 files i will get 1 row data the 1 row with the header 10 times.

I only want the header 1 time in my file.
Maybe there is a way to merge .csv with the same header ?
