Error uploading xlsx V4

Hi, i always get the error importing file message. I used Version 4 of Samplefile.
Using the interacive uploader there is no error before uploading. i dont get it.

Hi @Stiffler,

Are you uploading a CSV or XLSX?

XLSX like the template is

Hi @Stiffler,

This may be the issue. The template is a CSV. If you upload as a CSV it should work normally as well. You can export as CSV from spreadsheet editors like Google Sheet, Microsoft Excel, Apple Numbers, etc.
