Frequently Asked Questions

What counts as a duplicate?

Any item that appears two or more times in the list. Items that appear only once are left out of the result.

Are items matched exactly?

Yes. Items must match character for character, so “Apple” and “apple” are treated as different unless you make them consistent first.

In what order are duplicates shown?

In the order they first appear in your list, each with the number of times it occurs in brackets.

How is this different from grouping items?

Grouping shows every item with its count. Finding duplicates shows only the items that repeat, which is handy when you just want to spot the repeats.

Is my list uploaded?

No. The check runs in your browser and your list never leaves the tab.
