FAQ
What does "Numeric" sorting do?
It extracts the first number found in each line (positive, negative, or decimal) and sorts by that value - useful for lists like "10 items", "2 items" that should sort by quantity, not alphabetically.
What happens to blank lines?
They are removed automatically before sorting, so your output never has stray empty lines mixed in.
How does "Remove duplicates" decide what counts as a duplicate?
Two lines are duplicates if they match exactly (or match ignoring case, if "Case-insensitive" is also checked) - only the first occurrence of each is kept.
Is my text uploaded anywhere?
No. Sorting happens entirely in your browser as you type - nothing is sent to a server.
