CSV Exception Finder
Compare an expected CSV against an actual CSV, surface missing records, duplicates and amount mismatches, quantify exposure, and export the exception list. Your files stay in your browser.
Use it for recurring controls: invoices vs payments, commissions vs payouts, vendor statements, inventory, settlements, customer records, and any workflow where two systems should agree.
Need the management layer too? The Operator Control System turns exceptions into owners, corrective actions, controls, weekly review and automation priorities.
