Hello there, @Megakun. 

I'm here to  help you with import your transactions using a CSV file.

When importing a CSV file, the accepted file formats are the 3 and 4 column formats. The 3 column includes the Date, Description and Amount. On the other hand, the 4 column format includes the Date, Description, Credit and Debit.

For more details, you may refer to this article: Import bank transactions from Excel CSV file
