Remove Duplicates from Video Game Product and Catalog Data

Video game databases are heavily duplicated because the same title is released on multiple platforms, in several editions, and sold through different digital storefronts with unique identifiers for each. A single game might appear as 'Elden Ring (PS5)', 'ELDEN RING - Deluxe Edition', 'Elden Ring Steam Key', and 'Elden Ring (Standard)' in a retailer's catalog. dataclean.to matches game records by normalizing titles, extracting platform and edition designations, and clustering entries that represent the same base game across different distribution formats.
The Problem
Duplicate game listings complicate retail operations and distort sales analytics. A game store with the same title listed multiple times cannot accurately report how many copies of a game it has sold across all formats. Digital key resellers with duplicate product pages compete against themselves in marketplace search results. Review aggregation sites that cannot link platform-specific listings to a single game page fragment their review score across entries. Wishlist and recommendation systems that show the same game under three different names fail to recognize when a user already owns or has wishlisted the title. Price tracking tools that cannot match duplicates across storefronts miss deals and produce incomplete comparison data. Schema.org VideoGame structured data specification
How to Fix It
1
Export game catalog data from all storefronts
Combine product listings from your retail platform, digital storefronts, and distributor feeds. Include game title, platform, edition, publisher, release date, price, UPC or digital store ID, and genre.
2
Upload to dataclean.to
Upload the CSV. The tool normalizes game titles by stripping platform tags, edition suffixes, and promotional text, then groups records by base title and publisher to identify listings that represent the same game.
3
Review duplicate game clusters
Examine groups of listings flagged as the same title. The tool distinguishes between true duplicates and legitimate variants like platform-specific or collector's editions, showing which fields match and which represent intentional differences.
4
Merge or link related listings
Consolidate true duplicates into single entries. For platform variants you want to keep separate, link them under a common game identifier so aggregate sales and reviews can be tracked at the title level.
5
Export the clean game catalog
Download the deduplicated CSV and update your product database. Each game now has a clear hierarchy of platform and edition variants under one canonical title with no phantom duplicate listings.
Frequently Asked Questions
How does the tool handle Game of the Year and Definitive Edition re-releases?
Special editions with additional content are flagged as related to the base game but kept as distinct listings when they include different content. The tool clusters them so you can link them to the same title while maintaining separate product pages for each edition.
Can it match the same game across different regional names?
Games with different regional titles are matched when they share the same publisher and release date. The tool flags them for review so you can confirm the regional naming relationship and merge or link the entries.
What about DLC and expansion packs that share the base game name?
DLC entries that include the base game name plus a subtitle are distinguished from the base game listing. The tool does not merge them but flags them as related entries so you can organize the DLC under the parent game in your catalog structure.
