How can I solve this problem? I can not import the bank statement. Is there any way to control bank checks?
It would be very strange if a statement exported from a bank did not include dates of transactions. But, if it does not, you cannot import it as it is. First, see if your bank offers exports in any other format, because CSV files give the most trouble due to lack of standard formatting. If that is impossible, the only thing you can do is modify the file in a spreadsheet before importing it.
The file has date, so I find it strange. They only offer this format.
Are the columns labelled in the CSV file? Are they actually dates, not text? And does their format match your date preference setting?
