Frequently Asked Questions
No. This tool operates entirely on the client side via your web browser. All array shuffling, deduplication, and text formatting happen locally on your computer or phone. Your data is 100% private.
Yes. The tool relies on heavily optimized JavaScript arrays capable of parsing, shuffling, and sorting tens of thousands of lines in milliseconds without crashing your browser.
Our deduplication algorithm strictly targets exact matches. If one line has a trailing space and another does not, the computer sees them as different strings. Ensure you have the "Trim Spaces" option checked to clean up invisible differences before sorting.
