The most common task when using Quickbooks is to enter transactions. Often banks provide transactions through online banking. Instead of entering transactions by hand from the printed paper statement, check first which format your online banking provides.
OFX, QFX, QBO - transactions have the date, amount, payee name, optional description, an optional check number for checks, and unique transaction id
QIF - transactions have the date, amount, payee/description, check number
CSV - transactions have the date, amount, payee/description, check number
PDF - transactions are presented inside to printed bank or credit card statement
QuickBooks 2018-2020 imports QBO (web connect) files as the easiest option to import transactions. Quickbooks provides the Bank Feeds interface to "match" transactions to vendor records after import and assign expense/income accounts and add transactions into the register.
If your bank provides transactions in QBO format, this is the easiest option to import into Quickbooks as Quickbooks imports QBO (Web connect) format, simply import this file into Quickbooks or Quickbooks online
If your bank provides QBO files, but does not provide direct online download, Quickbooks may not import the QBO file from your bank, use Bank2QBO to make your QBO file importable by Quickbooks
QBO format is essentially OFX format with added details related to Quickbooks
Use Bank2QBO to convert OFX files to QBO format and import into Quickbooks

Quickbooks Desktop imports the IIF format, which allows to specify vendor name and expense/income account (category) and import transactions directly into the register.

After CSV/Excel file is edited, use Bank2IIF to convert to IIF
For older Quickbooks, IIF format is only option to import. Use the instructions above to get your data into IIF format
