What would be the proper way to "create" a .xlsx file and "transfer" the content of this obj into it? I took the example of an Excel file, but my question would extend to any kind of binary file.

It depends on how the .xlsx was put in to the database and then 
extracted into R, but if it's just a copy of a file from disk, 
writeBin() will write it without changes.
