Review important results before use.
Does it do fuzzy matching?
No. Matching is exact after your selected case and whitespace rules. Similar names, accents and misspellings are not automatically merged.
Does it count duplicate occurrences?
This is a set comparison. Repeated items collapse; it does not reconcile quantities or match duplicates one by one.
What can I export?
A CSV with Group and Item columns. Formula-like cells are prefixed with an apostrophe for safer spreadsheet opening.
