I received raw data in iot central and I want to export it as a csv file. Blob seems to have this feature, but I haven't figured out exactly how to do it.
Sorry I'm not very familiar with Blob, thank you very much for all your help

I created a template in iot central, but there was no option for creating a new device, and there was no way for the template to be published.
I did the same thing before, and it worked, maybe I forgot something! In addition, I would like to ask about the details of sending data to BLOB and exporting to csv, thanks a lot!
