    Frequently asked questions

    Is the order kept?
    Yes. Without sorting, the lines stay in their original order and only repeats are removed.
    What is natural sort?
    It reads numbers inside the text as numbers, so file2 comes before file10. A plain A to Z sort puts file10 first.
    Does it handle big lists?
    Yes. Lists with hundreds of thousands of lines usually work, depending on your device.
    Is my text uploaded?
    No. Everything runs in your browser.
