What is bank statement conversion?

Bank statement conversion is the process of converting a bank statement (PDF, image, or digital file) into structured, machine-readable data, such as Excel (XLSX) or CSV. Our AI platform automates every step, from file intake to validation, so you can convert bank statements to Excel or CSV files in minutes with high accuracy, ready for reconciliation, analysis or upload to your finance systems.

What is bank statement data extraction?

Bank statement data extraction reads a statement and pulls out key data points (e.g., account holder, account number, opening/closing balances and every transaction line). Affinda’s AI turns unstructured statements into clean Excel or CSV formats that slot straight into your general ledger, BI tools or downstream workflows.

Our platform blends reading-order models, OCR, LLMs, RAG and agentic workflows to extract data from any layout or language with high accuracy and faster processing times, ideal for both one-off conversions and bulk processing.

Transaction-line extraction captures every row in the statement’s transaction table and preserves the relationships between columns (date, description, debit/credit, running balance etc.). Our complex-tables capability “reads” your lines with impressive contextual understanding, ensuring clean, analysis-ready Excel or CSV files.
