No manual typing
OCR + AI
GoBD-ready

Manually retyping old paper statements is slow and error-prone. Scanned PDFs cannot be copied, so every booking has to be keyed into Excel or DATEV by hand.

KontoCSV does this in seconds: upload the scan, the AI extracts bookings, normalizes them, and delivers a structured CSV/DATEV export. No copy & paste, no typos.

Time saved in numbers

5 minutes per page when typing vs. ~30 seconds with KontoCSV. On 120 pages that saves about 10 hours.

IBANs, booking texts, value dates, and amounts are validated automatically.

Why paper scans are so painful

Common issues when typing

Skewed scans, stamps, or handwritten notes.

OCR mix-ups: 1 vs. I, 0 vs. O, decimal separators.

Unstructured text: dates, IBANs, and amounts get merged.

No plausibility checks for balances or signs.

What the solution needs

Robust OCR for slightly faded or skewed scans.

Field mapping: date, value date, description, IBAN, amount.

Validation against balances and totals.

Export profiles for DATEV, Lexoffice, sevDesk & banking apps.
