FAQ

Q: Will empty lines be preserved when deduplicating by line?

A: By default, empty lines are also treated as lines. If there are multiple empty lines, one empty line will be preserved after deduplication. You can pre-delete empty lines for cleaner results.

Q: What does the case sensitive option do?

A: When case sensitive is enabled, 'Hello' and 'hello' are treated as different content; when disabled, they are treated as the same. Choose the appropriate setting based on your data needs.

Q: What does the keep original order option do?

A: When enabled, deduplicated content maintains the original appearance order; when disabled, results may be sorted alphabetically or otherwise. It's enabled by default to maintain data coherence.

Q: How are punctuation marks handled when deduplicating by word?

A: When deduplicating by word, punctuation is treated as delimiters. 'hello,' and 'hello' are both treated as the word 'hello'. This helps in more accurate word counting.

Q: How can I see exactly which content was removed?

A: Enable the 'Show Duplicate Content' option, and the tool will list all content identified as duplicates below, making it easy to verify the deduplication results.
