# Multi-Format Transaction Parser

When analyzing financial data spanning multiple years/sources, transaction CSV formats often differ (column names, date formats, transaction types). Build an adaptive parser that detects format variations, handles schema mismatches gracefully, and consolidates into a unified dataset. Use pandas with conditional logic to map columns by position or fuzzy matching, then validate totals across years to catch parsing errors.
