The reason to buy

What this saves you from building

You are not paying for a file count. You are skipping the failure handling, verification, documentation, and operational edge cases behind the feature.

CSV and restricted XLSX parser hardening

Start with the defensive path already connected and tested.

Schema mapping, normalization, validation, and duplicate handling

Use an explicit data model and lifecycle instead of stitching together examples.

Transactional staging, promotion, rollback, reports, and audit history

Keep reproducible QA and operator-facing evidence from the first integration.

What's included

Connected infrastructure, ready to adapt

Config-driven CSV and restricted XLSX ingestion
Flat scalar schema, exact mappings, and normalization
Row-level and cross-field validation
Composite-key duplicate detection
Preview, dry-run, and separated reports
SQLite staging with atomic promotion and owner-scoped rollback
Deterministic replay and transactional audit history
102 tests across host, clean, Docker, Compose, and extracted-package paths

Screenshots / demo

The product is the visual.

Every frame uses synthetic fixtures. No customer data, live keys, or private environments.

CSV import CLI quickstart — 01Stage, preview, and promote a synthetic CSV through the included CLI.

Config-driven column mapping and normalization — 02Keep destination fields, mappings, and duplicate policy explicit and reviewable.

Invalid row separation and safe error reporting — 03Separate invalid rows before target mutation and export redacted error details.

Transactional import and rollback history — 04Inspect the staged, promoted, audited, and owner-scoped rollback lifecycle.
