Good to know
What is the difference between duplicate lines and words?+
Line mode compares each complete line as one item. Word mode splits text at whitespace before comparison. Use line mode for lists of keyword phrases.
Does it merge plurals or similar meanings?+
No. Bag and bags, and words with similar meanings but different spellings, remain distinct. This tool does not stem words or compare meanings.
Can I use it on order or advertising reports?+
Paste only a keyword, ASIN or SKU column. Records with orders, sales or spend require business-specific aggregation; deleting repeated text is not a substitute.
What changes in the output?+
Only duplicate items and enabled blank-line cleanup are removed. Line mode can trim edges; word mode joins retained words with single spaces. Keep your original text to review changes.
