CatalogDiff: Compare CSV catalogs and instantly see what changed

Hey Product Hunt 👋 I built CatalogDiff after seeing how annoying it can be to compare large CSV catalogs manually and figure out what actually changed. CatalogDiff lets you compare two CSV files and quickly spot added or removed products, price changes, stock changes, SKU differences and other modified fields. The files are processed locally in your browser, so your catalog data doesn’t need to be uploaded to our servers. I’m currently focusing on ecommerce teams, agencies, suppliers and businesses that regularly work with product catalogs, migrations and data exports. I’d really appreciate your feedback — especially on what workflows or integrations you’d like to see next. Thanks for checking out CatalogDiff! 🚀 Marco Founder of CatalogDiff
