Find duplicate IDs, missing transactions and amount mismatches across two CSV files. Processing stays in this browser; no network API, storage, or third-party tracking is used by this demo. Sample data is synthetic. Not a past customer project.
Comparison: exact ID (case-sensitive) and two-decimal currency amount; duplicate IDs are reported and excluded from one-to-one matching. IDs are treated as text. Limits: 5MB per input file, up to 20,000 records each. A UTF-8 BOM is accepted. Supports quoted CSV fields, including escaped quotes.
