What this audit tool actually checks
The tool performs four transparent checks. It looks for rows with the same normalised merchant description and amount, description words commonly associated with fees, words that can indicate recurring billing, and purchase amounts above a threshold chosen by the user. These rules create a review queue; they do not establish that anything is wrong.
A statement audit should always begin and end with the official statement. CSV exports can omit pending activity, change signs, shorten descriptions or format dates differently. Compare the number of imported transactions and inspect any parsing problem before relying on a flag.
Create a redacted working copy
A transaction review usually needs only date, short description and amount. Remove account identifiers, card numbers, addresses, balances, limits and unrelated columns before loading the file. Keep the original unchanged in secure storage. The redacted copy should be treated as financial information and deleted according to your needs after review.
Do not upload a statement from a work device if policy prohibits personal financial processing. Local browser operation reduces transmission, but it does not make every device, browser extension or shared profile appropriate for sensitive records.
How duplicate-looking flags work
Two rows are flagged when their cleaned description and absolute amount match. Legitimate duplicates are common: two meals at the same merchant, split shipments, instalments, repeated transport charges or separate cardholders. Conversely, a duplicate may use a slightly different descriptor and escape the simple rule.
Check dates, merchant locations, receipts, authorised users, refunds and pending-versus-posted status. Never accuse a merchant or another person based only on a keyword match. If a charge remains unrecognised, use the issuer’s official dispute or card-security process promptly.
Recurring-charge clues
Words such as subscription, membership, monthly or renewal can indicate recurring billing, but many merchants do not include those words. A flagged renewal may be intentional and valuable. Review cancellation terms, renewal notices and service access before deciding what to do.
A single statement cannot reliably identify recurrence. Comparing several complete periods can help, but this tool does not store history or merge files. Do not cancel a service that supports health, insurance, security, work or another person without understanding the consequences.
Fee keyword review
Fee-related words may highlight annual charges, late fees, cash-advance fees, foreign transaction charges, interest or other items. The description alone does not show whether the amount follows the agreement. Read the statement notes, card terms and issuer explanation.
Interest and fees may result from payment timing, promotional terms, cash-like transactions or previous balances. The tool cannot reconstruct the account calculation. Ask the issuer for a breakdown through a verified contact method when something is unclear.
Large transactions need context
The threshold is a personal attention level, not a definition of unusual spending. Set it in the statement’s currency and review the amount convention. A large refund, payment or balance transfer can be mistaken for a purchase when signs are interpreted incorrectly.
Large transactions can be easier to remember than small repeated charges. Use the flag to compare with receipts or plans, not to judge affordability. Financial circumstances and necessary expenses differ widely.
CSV limitations
This lightweight parser splits each line at commas and expects the first three columns to be date, description and amount. A quoted merchant description containing a comma can shift columns. Some exports use semicolons, separate debit and credit columns, parentheses or locale-specific decimal marks. Those formats require preparation or a more capable approved tool.
After loading, confirm row count and inspect representative amounts. If the output looks wrong, clear it rather than trying to reason from corrupted rows. The safe example demonstrates only the expected simple format.
A careful review workflow
- Download the official statement through the issuer’s verified service.
- Create a minimal redacted CSV working copy.
- Confirm columns, signs, currency and period.
- Run the local review and mark each prompt after checking evidence.
- Reconcile refunds, payments, transfers and authorised-user activity.
- Contact the issuer promptly through a verified channel for unresolved concerns.
- Delete unnecessary working copies and retain required records securely.
Security and scam awareness
Do not call a phone number from a suspicious message or search advertisement. Use the number on the official card, trusted issuer application or verified website. Never provide a one-time password, PIN, complete password or remote device access to someone claiming to investigate a charge.
Urgency, threats and requests to move money to a “safe account” are warning signs. The audit tool cannot detect social engineering or secure an account. Use official fraud reporting and emergency processes appropriate to the situation.
Method and limitations
Rows remain in memory for the current page. Descriptions are lowercased and punctuation is simplified for matching. Keyword checks are visible in the source logic. The tool does not connect to a bank, calculate interest, detect every recurring payment, prove fraud, file disputes, assess credit or provide financial or legal advice.
Frequently asked questions
Is the statement uploaded?
No. It is read locally.
Does a flag prove a problem?
No. Every result is a prompt for verification.
Which CSV format works?
Date, description and amount should be the first three comma-separated columns.
Can it dispute transactions?
No. Use the issuer’s verified process.
Should identifiers be included?
No. Use only a minimal redacted working copy.
