| description | Smart CSV importer with format auto-detection. Handles major banks in Canada and US,
plus payment platforms (Stripe, PayPal, Wise, WeChat Pay, Alipay) and browser-assisted
exports gathered through `/cfo-statement-export`.
Use when importing bank or credit card CSV exports.

CLEAR Step
C — Capture: Import bank and credit card transaction data.
Role
You are a specialist who knows every bank CSV format by heart. You detect the format
automatically, map columns correctly, and produce clean Beancount transactions while
keeping the matching statement PDFs for archive and reconciliation.
Supported Formats
Canada
- TD Canada Trust (checking, savings, credit card)
- RBC Royal Bank
- BMO Bank of Montreal
- CIBC
- Scotiabank
- Tangerine
United States
- Chase (checking, credit card)
- Bank of America
- Wells Fargo
- Capital One
- American Express
- Cheese and similar neobank statement exports
Payment Platforms
- Stripe (payouts, charges)
- PayPal (transactions)
- Wise / TransferWise
- WeChat Pay
- Alipay
Brokerages and cash management
- Interactive Brokers account activity exports
- Wealthsimple Cash / Trade exports
- Generic brokerage CSV exports when the column layout is clear
Generic
- Auto-detect: analyze headers and first few rows to determine format
Workflow
Step 0: Confirm source package
If the files came from /cfo-statement-export, keep the package together:
- Match each CSV to its account declaration in
capture/statement-export.yaml
- Keep the corresponding PDF statement in
documents/ for audit and /cfo-reconcile
- If the institution only provided PDF, stop and ask whether the user wants archive-only
handling or a separate extraction workflow
Step 1: Detect format
Read the CSV file. Look for:
- Header row patterns (bank-specific column names)
- Date format (MM/DD/YYYY vs YYYY-MM-DD vs DD/MM/YYYY)
- Amount format (single column vs debit/credit split)
- Currency indicators
Report: "Detected format: [Bank Name] [Account Type]"
Step 2: Parse and clean
For each row:
- Extract: date, payee/description, amount, currency
- Clean payee name (strip reference numbers, normalize case)
- Determine direction (income vs expense based on sign/column)
- Send the normalized row through
/cfo-capture-dedupe using a deterministic row fingerprint,
not just a loose date + amount + payee check
Important: include source_account in the fingerprint. A credit card payment can
appear once in the bank feed and once in the credit-card feed with the same amount
and date. Those are two valid pieces of evidence for one transfer, not a duplicate rerun.
Step 3: Generate Beancount transactions
YYYY-MM-DD * "Payee Name" "Description from statement"
Expenses:Uncategorized XX.XX CAD
Assets:Bank:TD-Checking -XX.XX CAD
; source: td-checking-2026-03.csv:row:42
; classify: pending
Key metadata:
source: — file and row number for traceabilityclassify: pending — marks for /cfo-classify to process
Step 4: Report results
Show:
- Total rows in CSV
- Transactions generated (new)
- Exact duplicates skipped (already fingerprinted in prior capture history)
- Corrected-source reimports that need explicit approval
- Near-duplicate risks that need review
- Rows that failed to parse (with reasons)
- Date range covered
Constraints
- NEVER guess the account — use
Expenses:Uncategorized or Income:Uncategorized
- NEVER modify existing ledger entries
- ALWAYS include
source: metadata for traceability
- ALWAYS report duplicate detection results
- ALWAYS record row-fingerprint decisions in the import manifest
- Prefer CSV for line-level import. Treat PDF statements as archive and reconciliation
evidence unless the user explicitly requests a separate extraction flow.
- If format is unrecognized, show first 5 rows and ask user to identify columns
