I'm using XXX_FULL_API to download an Excel sheet.
It's working fine.
Now, I have a request to add a title consisting of the user's name, date and time to the top two rows of the Excel sheet (and push the data down two lines)
XXX_FULL_API has two export parameters HEADER_1 and HEADER_2, but they do not do anything for me.
Can anyone suggest a solution?
