Deduplicator removes duplicates from a list with optional fuzzy-matching. Simply paste your list into Deduplicator and hit ‘Find Duplicates’. Deduplicator will identify duplicate items and show them in a preview window. Hit ‘Remove Duplicates’ to proceed. Your list has now been deduplicated and contains only unique elements. To account for variation in capitalisation and spelling, you may wish to use fuzzy matching. Moving the fuzziness slider one notch towards ‘fuzzy’ will result in a case-insensitive comparison.
With some experimentation on the range between ‘strict’ and ‘fuzzy’, the operator should provide a satisfactory level of deduplication.
