This tutorial shows how to convert a CSV file from your bank or credit card statement to IIF format and import into Quickbooks. We will use CSV2IIF utility.
See below steps for the Windows version.
The IIF format allows better control for imported data than the QBO format and importable by older Quickbooks.
CSV file must have Date, Amount, Category (expense/income account), Payee (Vendor in Quickbooks), Bank or Credit Card Account name.
Click 'Change +/-' to reverse amount signs for the whole file. Useful for Credit Card files with positive amounts for expenses.
Review transactions before importing, and click the 'Convert' button to create an IIF file.
Confirm the file name and location.
Now the IIF file is created, let's switch to Quickbooks and import created IIF file. Make sure to backup your Quickbooks data file, before any IIF import.
In Quickbooks, click 'File' - 'Utilities' - 'Import' - 'IIF Files'. Locate the IIF file you've just created.
Done! Transactions are imported.
Review transactions in Quickbooks after importing.
