Frequently asked questions
Does sort preserve blank lines?
Yes. Blank lines are included in sorting (empty strings sort first).
How does deduplicate work?
Removes exact duplicate lines, keeping the first occurrence. Case-sensitive.
What does title case do?
Capitalizes the first letter of each word on every line.
Is my text sent to a server?
No. All transforms happen in your browser.
