ZUGFeRD Viewer

Purpose-built to access and interpret ZUGFeRD data without manual XML digging. The tool accepts XML or PDFs with embedded XML, detects the profile version, and extracts header fields and line items into a consistent schema. Conceptually, it separates structure from presentation: the source document is parsed to a structured data model that can be consumed by downstream systems. This enables developers to build integrations, auditors to verify correctness, and finance teams to accelerate reconciliation. Core features include automatic version detection, robust field mapping for invoice metadata (supplier, recipient, numbers, dates, currency, totals) and line-item details (descriptions, quantities, prices, line totals), plus outputs in JSON or CSV. Unique value lies in schema-aware extraction across profile variants and immediate exportability for ERP, data warehouses, and audit trails. Use cases cover supplier onboarding, integration projects, and compliance checks where precise extracted data matters. In practice, a user uploads a file, the tool parses embedded XML if present, validates required fields, and returns structured data along with basic validation signals. Outputs support programmatic consumption, enabling automated reconciliation and analytics. The tool focuses on data extraction and validation rather than rendering or editing invoices, ensuring deterministic results and traceable provenance for finance workflows.
