FAQ
How do I sort a list of lines alphabetically online?
Paste the list and choose Sort A→Z — it sorts instantly in your browser with no upload. Use Sort naturally when the lines contain numbers, so file2 comes before file10 instead of after it.
How do I remove duplicate lines?
Choose Remove duplicates. It keeps the first occurrence of each line and drops the rest; turn off Case-sensitive to treat Apple and apple as the same.
Is my list uploaded?
No — every operation runs locally and nothing is stored. It works with your Wi-Fi off.
What is a natural sort?
A sort that reads embedded numbers as numbers, so item2 sorts before item10. A plain alphabetical sort compares character by character and puts item10 first, which is almost never what you want for filenames or ids.
Limits
One operation at a time. Shuffle is seeded so the same list shuffles the same way within a session, which keeps the preview stable.
