What they did
He tested a ChatGPT mode that takes files and runs tasks in steps to compare the bank statement with the general ledger, and Codex to turn the comparison into a routine that repeats every month.
How it went
The author concludes that the tool cuts time spent on repetitive tasks but does not replace professional judgment. The account gives no numbers.
Good to know
Bank statements contain sensitive banking data: use an authorized corporate environment or anonymize first. Review every discrepancy flagged.
The prompt
I'm going to send you the bank statement for [month] and the ledger for account [code] (anonymized data). Compare entry by entry by date and amount, list what doesn't match in a table and suggest the likely cause of each difference. Don't change anything, just flag.
