The short answer

The Commonwealth Bank file has 4 columns, dates written as D/MM/YYYY and one signed amount column. QuickBooks Online wants a CSV with the columns Date,Description,Amount. So the date is rewritten as DD/MM/YYYY, the amount is written as one signed number, and the text columns are moved as in the table below.

Free. The Commonwealth Bank profile is one of the 5 free profiles of the converter. The free version writes the first 25 converted rows of a file; a licence removes that limit.

What the Commonwealth Bank CSV looks like

Note kept with this layout in the profile data: No header row, four columns. The day may have no leading zero; accept both. The source ignores the fourth column without naming it; it is treated as a balance to ignore.

Before and after: an invented example

Invented sample data. These four rows were made up for this page. They are not from a real Commonwealth Bank export and hold no real account, name or balance.

The source gives column positions only, so the headings below are the column number and what the column holds, not the bank's header text.

Do it by hand in a spreadsheet, free

These steps need no tool from this site. The cell references follow the column positions of the profile above; if your spreadsheet uses semicolons between formula arguments, replace the commas.

  1. Open the Commonwealth Bank CSV in a spreadsheet program through its import dialog. Set the date column (column 1) to Text so the program does not reinterpret it, and leave the amount columns as numbers.
  2. The file has no header row: row 1 is already a transaction. Do not delete it.
  3. Date: rewrite column A from D/MM/YYYY to DD/MM/YYYY (4/03/2024 becomes 04/03/2024). This bank's dates do not have a fixed width, so a position formula is not reliable: split the column into its parts (Text to Columns, or the split function of your spreadsheet) and join them again in the new order.
  4. Amounts: column B is already signed the way QuickBooks Online wants (money out negative). Copy it as it is.
  5. Text columns: fill Description (from column 3). Where several bank columns feed one column, join them with a separator such as " - ".
  6. Apply QuickBooks Online's own rules from its help page: Remove any zeroes (0) from the file and leave those cells blank. Remove the word 'amount' if it appears in the Credit or Debit column header. Remove the day of the week from dates (for example 20/11/2018 TUE). Correct any transactions that display numbers in the Description column. Mac users must save the file as a Windows CSV file. CSV files for credit card accounts may display transactions in reverse order.
  7. Keep only the new columns, put the header row Date,Description,Amount on top, save the sheet as a comma-separated CSV, and compare the dates, the direction of the amounts and the number of rows with your statement in QuickBooks Online's import preview.

Where this layout comes from

No bank supplied or approved this layout. It was copied on 5 October 2026 from a public open-source importer file kept by volunteers: firefly-iii/import-configurations, file au/commonwealth-bank/default.json

The lines used from the source: "headers": false, "delimiter": "comma", "date": "j/m/Y", roles: date_transaction, amount, description, _ignore

The QuickBooks Online rules come from the vendor's own help pages: quickbooks.intuit.com/learn-support/en-global/help-article/bank-transactions/format-csv-files-excel-bank-transactions-quickbooks/L4BjLWckq_ROW_en (named as text, not linked). The official page was fetched and read on the checked date.

Bank formats change. Banks alter their CSV exports without notice and vendors change their import rules, so this mapping can be out of date. If the preview looks wrong, use the manual column mapper.
