Hey Tim,
Yes, you can set up a wizard to upload xlsx and / or csv files. I’ve made you a short video demonstrating how to go about it

Notes:
- Here’s the test wizard you see in the video.
- Here’s the topic showing you what uploaded file attributes you have available for interpolation.
If you’re still having issues after following the above, let me know.
