KontoCSV is a cloud-based data extraction tool that converts PDF bank statements into structured CSV or Excel files for accounting and bookkeeping purposes. The software is designed primarily for the DACH market and focuses on bank statement formats commonly issued by German financial institutions. It is used by tax accountants, bookkeepers, and small businesses that need to transfer transaction data from non-editable PDF documents into digital accounting systems. Many banks provide account statements only in PDF format, which can limit direct data reuse. KontoCSV addresses this by extracting transaction-level information such as booking dates, value dates, transaction texts, counterparties, and amounts. The system applies automated text recognition and structured parsing methods to interpret the layout of bank statements and convert the content into tabular data. The resulting output can be downloaded in CSV or Excel format, depending on the selected export profile. Users can upload individual PDF files or process multiple statements in batch mode. When several files are uploaded at once, the system processes each document separately and provides the results either as individual downloads or as a consolidated ZIP archive. This functionality is intended to reduce manual processing time when handling recurring monthly statements or multiple bank accounts. KontoCSV offers different export configurations to improve compatibility with established accounting software solutions. These include a standard bank CSV format as well as structured exports aligned with DATEV Buchungsstapel, Lexware Office, and BuchhaltungsButler. The goal of these predefined formats is to minimize additional formatting work before importing data into accounting systems. The platform operates as a hosted web application and does not require local installation. Users access the service through a browser interface. The system includes a transaction history area where previously processed files can be reviewed and re-downloaded within a limited retention period. Uploaded source files and generated exports are automatically deleted after seven days. According to the vendor, the infrastructure is hosted within the European Union. Data transmission is encrypted, and the service is designed to align with GDPR requirements. The application does not require permanent storage of financial documents beyond the defined retention window. KontoCSV is positioned within the broader category of data extraction tools and document processing solutions. Its primary use case is converting structured financial information from PDF bank statements into machine-readable formats that can be integrated into bookkeeping workflows. It is intended for users who need a repeatable and standardized method of transferring transaction data from bank-issued PDFs into accounting environments without manual retyping.
