- Direct Answer
- OCR reads characters from a scanned bank statement PDF or image and returns raw text. FastOCR’s separate bank statement workflow organizes visible account, balance, and transaction fields into JSON, CSV, or best-effort XLSX and adds a review signal based on balance consistency and source-grounding checks.

Raw OCR and structured extraction are different
Raw OCR turns pixels into text. It may not preserve the relationship between a date, description, debit, credit, and running balance. A born-digital PDF may already have selectable text, but selectable text is still not the same as structured financial data.
For structured output, use the Bank Statement Converter. It returns JSON and CSV, with XLSX as a best-effort export. The Bank Statement API reference documents the fields and authenticated upload flow.
What the review signal means
The structured workflow reports whether its checks found an issue. It considers balance consistency and whether extracted values are grounded in the source statement. The result can include:
- needs_review: A workflow signal for routing the result to automation or human review.
- has_opening_anchor: Whether an opening balance was found.
- endpoints_tie_out: Whether the calculated and printed endpoints agree.
- chain_broken: Whether a running-balance sequence breaks.
- flagged_issues: Locations and reasons for items that need attention.
No review signal is a useful operating condition, not a guarantee. Compare important amounts with the original statement, and send flagged rows to a person.
When bank statement OCR is useful
- Making a scanned or photographed statement searchable.
- Preparing transaction data for spreadsheet review.
- Supporting bookkeeping and reconciliation work.
- Separating routine results from exceptions before a downstream step.
It is not a fraud detector, underwriting system, or substitute for financial approval controls. Statement layouts, image quality, missing balances, and unusual tables can affect extraction.
Limits and access
Sign-in is required. The trial covers one statement up to 20 pages. PDFs up to 50 MiB and PNG, JPG, JPEG, or WebP images up to 20 MiB are supported. Results are retained for about 30 days. Larger workloads use one-time statement packs that remain valid for 12 months; see the related pricing page for current options. The API is private beta and allowlisted per account.
Frequently Asked Questions
Is raw OCR the same as bank statement extraction?
No. Raw OCR returns recognized text. Bank statement extraction organizes fields and adds balance and source checks that create a review signal.
Does needs_review false guarantee correct data?
No. It means the configured checks found no issue. Compare important values with the original statement and keep your own approval controls.
Can I try the structured workflow?
Yes. Sign in to process one statement up to 20 pages. PDFs up to 50 MiB and PNG, JPG, JPEG, or WebP images up to 20 MiB are supported.
