Error code: SystemError. Conversation ID: 39860dcc-da09-45f3-a53e-17100c9bc81e
I've tried .csv, .xlsx, expressly adding data types to every row, having ChatGPT reformat and check for errors.
Tried uploading just the 20 row head.
Tried uploading just the most important 4 columns.
Something is very wrong here.
