Are you part of the Clean by Similarity API team? [Upgrade your plan](https://my.g2.com/clean-by-similarity-api/upgrade?utm_campaign=s3&utm_medium=claim-popup&utm_source=g2) to enhance your branding and engage with visitors to your profile! Clean by Similarity API finds duplicate contacts, leads, and company names in your spreadsheets — even when they're spelled differently across records. Unlike Excel's Remove Duplicates or your CRM's built-in deduplication, Clean uses fuzzy matching to catch real-world variants: "Acme Corp" and "Acme Corporation", "Jen Walsh" and "Jennifer Walsh", "Microsoft" and "Microsoft Inc." are all correctly identified as duplicates. Exact-match tools miss these entirely. Upload a CSV or Excel file, select which columns to match on, and preview your duplicate clusters before downloading. Match on a single column or combine name and company together for more reliable results — combining two weak signals into one strong match decision. Three output formats: a clean file with duplicates removed, your original file flagged with cluster IDs, or a review sheet showing duplicate groups with similarity scores for manual inspection before merging. Free for files up to 1,000 rows, no account required. Larger files from $4.99 per run — pay once, download immediately, no subscription needed. Built for marketing ops, RevOps, and anyone who needs a clean file before a CRM import, not a coding project. * * * Seller [Similarity API](https://www.g2.com/sellers/similarity-api) Discussions [Clean by Similarity API Community](https://www.g2.com/products/clean-by-similarity-api/discuss) Overview by Siyana Hristova Show More ## Top-Rated Alternatives [ ![GTM Studio - Powered by ZoomInfo](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "GTM Studio - Powered by ZoomInfo") GTM Studio - Powered by ZoomInfo 4.5/5(3,512) ](https://www.g2.com/products/gtm-studio-powered-by-zoominfo/reviews) [ ![Demandbase One](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Demandbase One") Demandbase One 4.4/5(1,988) ](https://www.g2.com/products/demandbase-one/reviews) [ ![Validity Engage](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Validity Engage") Validity Engage 4.5/5(989) ](https://www.g2.com/products/validity-engage/reviews) [ View All Alternatives ](https://www.g2.com/products/clean-by-similarity-api/competitors/alternatives) ## Clean by Similarity API hasn't been reviewed yet Used Clean by Similarity API?
