Duplicate field names Duplicate field names are not allowed ERROR

[ECjin]

In order to add this csv item to ArcGIS Online hosted feature layer, I deleted all other feature layers. However, even there has already no layer, the system still display the duplicate filed names error.

Make sure you don't have any null fields (empty columns) in the CSV.

[ECjin]

My data does not contain any null fields or even null values within the cells. They also don't contain spaces.

[JosephRhodes2]

Are you able to share the CSV?

[ECjin]

Yes, please find the files attached. Thanks for your help Joseph!

You have two columns named "Total Enrolments_P". (Column F and Column AB).

Thank you! I went as far as using the ChatGPT Code Interpreter to assess my work, and it didn't flag any issues lol. You spot it! Thanks again!

It's probably all the empty field names. Hard to say without seeing the actual CSV.
