Hi SorenNorrman ,
Thanks for your question.
Not for now, sorry. It's on our TO-DO list, but I can't give you an ETA.
Meanwhile, you can use spreadsheet software that follows the standard for CSV (Comma Separated Values). For example, you can import your Excel from Google Sheets and export it directly with the standard format. If you want to learn how to do so, please read this article.
Best Regards,
José Andres
