Hi James James
Thank your for reaching out on Microsoft Q&A!
I've looked around on the internet, and found the blog below. It's based on retrieving a CSV from Blob Storage, however it appears to follow the same use case.
Depending on your requirements this could help achieving your goals.
If you need more assistance, please share a sample CSV so I can create it in my test lab.
Please let me know if my response is helpful by clicking "Accept answer". Feel free to drop additional queries in the comments below.
