Import csv - data instead of file

Hi, I get csv data (not .csv file) from api, and I want to insert them to db. Is it possible? It looks like Import csv needs file. I tried to use Export csv before Import, to overwrite temp csv file and use it for import, but it wasn’t working too. Do you have any idea, please?
