Have you selected any columns in Data Import Tool before exporting?

Sorry, I have the same problem now and error reporting.
When I download the template I select the necessary columns.
I have to select the columns also in the xlsx file? How?

No only on export do you select rows.

Anyone can help? Please! I have to import more than 2000 items.

It is a german version but in the same format. Can you read it?
Thank you!

Hi @Marco
Please update your bench and try again. We have pushed a fix for the same. This is the issue because of the language of the template (if selected other than English).

Thank you so much Manas!
I will try it again after update. At the moment unable to access to
Best regards!

Perfect, it works! Thankyou!
