If your bank only provides transactions in a CSV file, you can format it in a way that it's recognizable in QuickBooks. This article will guide you through the steps: Format CSV files in Excel to get bank transactions into QuickBooks. We only have the English version, but it has screenshots for your visual reference.
You can always go back to this thread if you have other questions in mind.
