DeduplicationWizard is a program for the deduplication of Excel files (dedulplication software / dedupe software). Deduplication can be done using the telephone number, the email address and the postal address. When the deduplication is based on the postal address - i.e. name, street, postal code and city - the program then also considers typos, inverted words and additions. It is then a fuzzy or error-tolerant deduplication.
