Thank you for your interest in RadSpreadsheet. Indeed at the moment only copy and paste in plain text is supported. I've included your suggestion in our backlog and I've also logged an item about it in our Feedback and Ideas portal
. This copy and paste feature, however, is not in our immediate plans at the moment. You can like and follow the feedback item in order to receive any updates on the matter.
Please, let me know if you have any further questions.
