What is a Commonwealth Bank bank statement

A Commonwealth Bank bank statement is the official record of every transaction posted to your Commonwealth Bank account during a given period, along with the opening and closing balance. It is the same document your lender, landlord, or accountant will ask for when they need proof of income, proof of address, or documentation for a bank statement loan or mortgage. A Commonwealth Bank statement typically covers one month, but you can export any custom date range from online banking.

What Karchu does with your Commonwealth Bank data

Once the file is uploaded, Karchu extracts every transaction, normalizes the columns, and applies rule-based categorization. You see a dashboard within seconds with total income and expenses, category breakdown, top merchants, recurring subscriptions, and any anomalies worth a second look. Every categorization is explainable, so if a transaction lands in the wrong bucket you can open the rule that decided it and edit it once. The change applies retroactively across every Commonwealth Bank statement you upload.

Commonwealth Bank statement to Excel and CSV

Karchu works as a Commonwealth Bank PDF to Excel converter and a Commonwealth Bank statement to CSV converter. Upload a scanned or digital PDF and download a clean spreadsheet with dates, descriptions, amounts, and categories in separate columns, ready for QuickBooks, Xero, or your own workbook. There is no signup required to try a single statement, no bank login, and no aggregator like Plaid.

Commonwealth Bank export notes

CommBank CSVs use DD/MM/YYYY dates and a single signed Amount column. Karchu detects AU date format automatically.
