What does 'Ignore Case' do?
When enabled, 'Apple' and 'apple' are treated as the same line. Only the first occurrence is kept in the output.
What does 'Trim Whitespace' do?
When enabled, leading and trailing spaces are removed from each line before comparison. ' hello ' and 'hello' would be considered duplicates.
What does 'Find Duplicates' show?
It shows only the lines that appear more than once, along with how many times each appears. This helps identify which items are repeated.
Can I sort the output?
Yes! You can sort the unique lines alphabetically in ascending (A-Z) or descending (Z-A) order, or keep the original order.
Is my text data secure?
Yes! All processing is performed entirely in your browser using JavaScript. Your text is never sent to any server, ensuring complete privacy.
