Quick Answer & Overview

FastOCR converts legal discovery bank statements into structured Excel, CSV, and JSON files for forensic accountants and litigators. It reads transaction rows and balances and tells you whether each statement reconciles. Check dates and descriptions against the source.

Use the bank statement to Excel converter to convert your statements online.

Why Bank Statement Conversion Matters in Legal & Forensic Accounting

In divorce proceedings, probate disputes, commercial litigation, and bankruptcy cases, legal teams receive hundreds or thousands of pages of scanned bank statements during discovery. Paralegals and forensic accountants must extract and trace every dollar without introducing clerical errors that could damage case credibility.

How to Convert Bank Statements to Excel, CSV, or JSON

Converting bank statement PDFs into usable spreadsheets takes less than 30 seconds with zero manual typing.

1

Go to Bank Statement Tool

Open fastocr.org/bank-statement in any web browser on your computer, tablet, or phone.

2

Upload Your PDF

Drag and drop a digital PDF bank statement (up to 50 MiB). Scanned statements and photos are read with OCR and may need more review.

3

Download Verified File

Get an Excel (.xlsx) and a CSV file back. The page tells you whether the statement reconciles.

Common Challenges in Legal & Forensic Accounting (And How FastOCR Solves Them)

Traditional document OCR tools produce unaligned tables and miss critical financial figures. Here is how our purpose-built engine fixes those issues:

Discovery PDFs with watermarks and bates stamps

Impact: Stamps and watermarks get mixed into copied transaction text.

FastOCR Solution: FastOCR reads the transaction rows of each statement. Scanned discovery pages are read with OCR and may need more review.

Risk of clerical error in courtroom financial evidence exhibits

Impact: A single miskeyed deposit or balance number can undermine expert witness testimony.

FastOCR Solution: Automated multi-tier balance tie-out checks verify the arithmetic validity of every transaction sequence.

Tracing multi-year transaction flows across hidden or undisclosed bank accounts

Impact: Manual data entry across 5+ years of records costs tens of thousands of dollars in billable paralegal time.

FastOCR Solution: Extract multi-year statement records into consolidated Excel workbooks in minutes.

Automated Reconciliation & Mathematical Verification Engine

Deterministic mathematical audit protocols that confirm extraction integrity before data enters downstream systems.

Unlike generic character-recognition systems that treat bank statements as unstructured blocks of text, FastOCR executes an advanced, multi-stage mathematical verification protocol. Every document undergoes deterministic balance reconciliation, bounding-box canvas anchoring, and continuous arithmetic validation across all transaction rows.

1. Dual-Entry Running Balance Parity

For every transaction \(n\) across the statement ledger, the engine mathematically enforces the continuity condition:

Balance(n) = Balance(n - 1) + Credit(n) - Debit(n)

Any non-zero delta immediately isolates the exact row causing a discrepancy.

2. Statement Endpoint Tie-Out

The engine extracts global statement anchors and proves the aggregate sum consistency:

Opening Balance + Sum(Credits) - Sum(Debits) = Closing Balance

Validates that zero transactions were truncated, omitted, or double-counted.

3. Source-Grounding Bounding Box Validation

Extracted numerical tokens are bi-directionally cross-referenced with exact high-resolution canvas coordinates on the original PDF raster. If optical degradation or character ambiguity falls below deterministic confidence thresholds, the system flags the specific coordinate for human inspection.

Deterministic Verification Confirmation Signals

Web App and API Status

Bank Statement API

Use the website, or send statements from your own code with one API key and the same statement pages.

1. Interactive Web UI

Upload a digital PDF bank statement in your browser. The page says whether it reconciled, and you download Excel or CSV.

2. REST API

Create a statement, upload the file and poll until it is completed to get JSON, CSV, Excel or QuickBooks files. It shares the web balance.

3. Questions

If the API does not fit what you are building, contact us and tell us what you need.
