I hope some one can help me.
Now, I want to generate a csv file about my sales order, but I think existing magento 2 csv format is not my expectation.
Could anyone can help me how to generate the below CSV file format through magento 2 admin export function.
The below image is my expect result:
In Sales -> Orders section of Magento 2 you can export to get the CSV file with predefined set of columns.
Unfortunately, there is no default means export ordered items and their qty (as in your screenshot). So you need to use some script to select out info or extension.
