What is Remove Duplicate Words?

FAQ

How is a 'word' defined?

A word is any sequence of non-whitespace characters separated by spaces, tabs, or line breaks. Hyphenated words like 'high-level' are treated as single words.

Does the tool preserve punctuation?

Yes — punctuation attached to words is preserved. 'Hello,' and 'Hello' are considered two different words because the first has a comma.

What happens with the 'Within each line' option?

When enabled, the tool deduplicates words independently on each line. So 'the cat and the dog' becomes 'the cat and dog' on that line, but 'the' can still appear on other lines.
