Frequently asked questions

Is comparison case-sensitive?

By default, comparison is case-sensitive. "Apple" and "apple" are treated as different entries.

Does it sort the list after removing duplicates?

The original order is preserved by default. Sorting options may be available separately.

Does it handle large lists?

Yes. The tool processes large line-based lists efficiently in the browser.
