Apply and inspect the result
Select Remove Duplicate Words when the input and settings are ready. In the saved example, the result begins: "apple, banana, orange".
Punctuation stays attached to its token, so word and word, can count as different entries. This does not analyze word roots or meaning.
Result overview compares the original token count with the retained unique tokens and shows Duplicate words removed. Words are separated by whitespace and punctuation stays attached, so the report follows the input tokens rather than recounting the joined output.
Result overview distinguishes changed, unchanged and empty results. An unchanged result means the selected operation did not alter the text; an empty result can be the expected outcome of removal or extraction.
