Features and how to use them

How this transformation works
Tokens are separated by whitespace. With Match case off, differently capitalized forms share a comparison key while the first spelling is retained. The Separator value joins the unique tokens; the initial separator is a comma followed by a space.

Opening and applying the tool
The entry screen accepts one UTF-8 TXT, CSV, JSON, XML, HTML or HTM file and opens the editor. Imports are text content, not a PDF or Word conversion. Review the source and choose Remove Duplicate Words when ready. Editing or importing alone does not apply the transformation.
Review, save or continue
Check the report before saving or continuing with the text.
Using the finished text
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. Copy the reviewed text or use the download icon to save UTF-8 TXT. Editing the result hides the calculated details until you run the tool again. Continue to offers compatible next tools for the current text and their limits. Review the transferred text before running the next operation.
