Merge Games

This tool merges two game datasets into a unified catalog, enabling deduplication and dataset consolidation for analytics and catalog maintenance. It is suited for data engineers, catalog managers, and product teams integrating publisher catalogs, storefront listings, or player databases. Conceptually, you provide two inputs (A and B) as lists of game records or IDs, then select a merge rule (union, intersection, or custom) and configure field mappings. The system normalizes common metadata, matches on IDs when available, and uses title and release_year fingerprints as a fallback for fuzzy matching. The core features include deterministic output, an auditable merge map, and options to export in JSON, CSV, or JSONL formats. Use cases include building a single storefront catalog from multiple sources, deduplicating a publisher list prior to analytics, and preparing data for recommendation systems. Unique value lies in its transparent conflict resolution and traceable lineage of each merged item, which supports reproducibility in data pipelines. The tool is designed to scale with large catalogs and to integrate into existing ETL workflows with minimal handoff.
