Frequently Asked Questions

Is this case-sensitive?
Yes, "Apple" and "apple" are treated as different lines. If you need them to be the same, convert your text to lowercase first using our Case Converter.
Can I sort my list without removing duplicates?
Currently, the Sort function also removes duplicates to ensure the cleanest possible list.
Is there a limit on lines?
There is no hard limit, but browser performance depends on your device. We have tested lists up to 50,000 lines smoothly.
