GUIDE & INSIGHTS
Guide: DATEV EXTF Header & Row Validation Rules
The DATEV EXTF format is the official standard for exchanging transaction data between ERP/accounting software and DATEV Accounting systems. A compliant EXTF file must feature a precise header in line 1 specifying version indicators, client/consultant numbers, fiscal year constraints, and data domain attributes. Followed by header columns and valid accounting lines, common issues include invalid date syntax (DDMM), unescaped text strings, or improper decimal separators in transaction values. Our online DATEV Export Validator performs local client-side checks to isolate header corruptions and row level anomalies before tax advisor submission.
