Bank Statements to Excel at Scale: Batch Processing and Normalization
Techniques for converting multiple bank statements to Excel in bulk while keeping schema consistent across months and accounts.
Batch Processing Strategy
Define a target schema (date, description, debit, credit, balance, account) and enforce it across files to keep analysis consistent.
Normalization
Standardize payee names and categories. Create mapping rules for recurring descriptions to reduce noise in pivot tables.
Quality Gates
- Row count per day looks reasonable
- Sum of debits/credits aligns with monthly totals
- No header/footer text leaked into the dataset
