Why doesn't all the rows import successfully

Hi, I have a data set that contains 4276 rows and when I import the data set it shows that only 3721 rows have been imported successfully. Would anyone have an idea on why this maybe?
Many thanks

Does it give you an error on the import?

Hi @Courxand!
Did you resolve your issue? If not, please provide the error details.

Thanks!
