AboutFuzzy Dedupe
Find and merge similar records (e.g. "Jon Doe" vs "John Doe").Category: Cleaning & PreparationCleaning a CRM export where the same customer was typed with slightly different spellingsMerging duplicate company names collected from different sales repsConsolidating a contact list built from multiple sign-up forms with inconsistent formatting
The Fuzzy Dedupe tool is compatible with:.Run Fuzzy Dedupe after Logical Dedupe has already removed the exact-match duplicates, so it only has to catch the harder, spelling-variant cases, then use Fuzzy Join if you need to match this cleaned list against another dataset.Fuzzy Dedupe catches near-duplicate records that an exact match would miss, entries like "Jon Doe" and "John Doe," or "Acme Corp." and "Acme Corporation." It scores string similarity between values using fuzzy matching algorithms and merges records that cross a similarity threshold you can adjust, consolidating them into a single clean entry.
Frequently Asked Questions:
How does it catch near-duplicates like "Jon Doe" vs "John Doe"?
It uses fuzzy string matching to score how similar two values are, rather than requiring an exact character-for-character match.
Will it merge records automatically or just flag them?
It finds and merges similar records that pass the similarity threshold, consolidating them into a single entry.
Built for anyone cleaning CRM, contact, or vendor lists where the same real-world entity was entered inconsistently across sources.
