Bank Statement API

Bank Statement Data Extraction API

Bank statement data extraction converts financial documents, PDFs, scanned images, or digital statements, into structured, machine-readable records. ByteIt's Bank Statement OCR API reads both statement-level metadata (account holder, IBAN, BIC, statement period, opening and closing balances) and every transaction row (date, description, debit, credit...), regardless of bank layout or language. The engine handles native digital PDFs, scanned paper statements, and phone-captured images without template configuration.

Benefits

Eliminate manual data entry from bank statements, reducing per-statement processing time from minutes to seconds and freeing finance teams for higher-value work.

Cut operating costs by up to 80% by replacing human keying with automated extraction that runs at scale, from a handful of statements to thousands per month.

Accelerate lending, mortgage, and credit-decisioning workflows by feeding validated transaction data directly into underwriting systems within seconds of upload.

Improve audit readiness and compliance by maintaining a complete, timestamped extraction log for every statement processed, with no data left in unstructured PDFs.

How it works

  1. Step 1

    Upload

    Send the document to the API as a file or a URL no special formatting required.

  2. Step 2

    The engine reads the document

    The engine analyzes the page layout and identifies the content that matters. The extraction engine reads both the header block and the full transaction table of any bank statement, native PDF or scanned, identifying account metadata, statement dates, running balances, and every individual transaction row without requiring a predefined template.

  3. Step 3

    Structured JSON is returned

    Every extracted element comes back as structured JSON, positioned and typed, ready to feed into downstream systems.

  4. Step 4

    Confidence-based review

    Each field carries a confidence score, so low-confidence results can be routed for human review instead of trusted blindly.

Features

Extracts statement-level fields including bank name, BIC, IBAN, account holder name and address, statement period, opening balance, closing balance, total credited, and total debited.

Parses full transaction tables with date, description, debit and credit amounts, running balance, refunds, and currency, even from statements without visible gridlines.

Accepts PDF, JPG, PNG, TIFF, and other standard formats, both native digital files and scanned or photographed paper statements.

Performs automatic balance reconciliation, flagging statements where opening balance plus total credits minus total debits does not equal the closing balance.

Supports multi-page statements, detecting account boundaries and statement period breaks across long documents without manual splitting.

Use cases

Loan and mortgage underwriting

Lending teams receive hundreds of bank statements from applicants each week. ByteIt extracts income deposits, recurring debits, and running balances from every statement and outputs structured JSON. The data can be piped directly into underwriting engines or loan origination systems via API, eliminating manual income verification and reducing decision cycles from days to minutes.

Account reconciliation for finance teams

Finance departments reconcile bank statements against internal ledgers monthly. ByteIt's extraction engine reads every transaction row and balance summary from the statement and flags mismatches through built-in balance reconciliation checks. The structured output can be exported to CSV or JSON and fed into accounting software for automated matching against book entries.

KYC and financial compliance checks

Compliance teams need to verify income sources, detect unusual transaction patterns, and maintain audit trails. ByteIt extracts account holder details, transaction histories, and aggregate totals from customer-submitted statements. The structured data integrates with compliance dashboards and case-management tools through workflow automation platforms such as n8n, Zapier, or Make.

Personal finance and budgeting automation

Fintech apps and budgeting platforms ingest user bank statements to categorise spending, track cash flow, and generate financial insights. ByteIt's API converts statement PDFs into transaction-level structured data that can be pushed into categorisation engines, spending analytics dashboards, or personal financial management tools.

Debt collection and credit management

Collection agencies and credit management firms process bank statements to assess repayment capacity and verify income. ByteIt extracts salary credits, regular debits, and running balances from submitted statements, enabling automated affordability assessments and compliant collection workflows without manual document review.

Frequently asked questions

What file formats does the Bank Statement OCR API support?

ByteIt accepts PDF (both native and scanned), JPG, PNG, TIFF, and BMP. The engine automatically detects whether the file is a digital PDF with selectable text or a scanned image and applies the appropriate extraction pipeline.

Can it handle multi-page bank statements?

Yes. The engine processes multi-page PDFs and images, detects account boundaries and statement period breaks, and returns page-level metadata alongside the consolidated extraction. There is no need to split the document before upload.

How does the API handle low-quality scans or photos of bank statements?

ByteIt applies preprocessing steps such as deskewing, contrast enhancement, and noise reduction before OCR. While a clear scan yields the best results, the engine is trained on varied-quality data and can extract usable information from moderately skewed, faded, or photographed statements.

Does the extraction include balance reconciliation?

Yes. The engine performs an automatic check: opening balance plus total credits minus total debits should equal the closing balance. Statements that do not reconcile are flagged so your team can investigate discrepancies without manually rechecking every row.

How do I integrate the Bank Statement API into my workflow?

ByteIt exposes a REST API. You can send documents via direct HTTP requests or use workflow automation tools such as n8n, Zapier, or Make to connect the output to your accounting system, lending platform, or compliance dashboard. Webhooks are available for asynchronous processing.

Can I export the extracted data to Excel or CSV?

Yes. The API returns structured JSON by default, which you can convert to CSV, Excel, or XML. The data is organised into statement-level fields and a transaction table, making it straightforward to load into spreadsheets or accounting software.

What languages and regional formats are supported?

The engine reads bank statements in multiple languages and alphabets, covering US, EU, and UK statement formats. It handles date formats, currency symbols, and decimal separators from different regions without manual configuration.
