What's the difference between case-sensitive and case-insensitive deduplication?

Case-sensitive dedup treats 'Apple' and 'apple' as different lines (both kept). Case-insensitive dedup treats them as duplicates (only the first occurrence is kept). Use case-sensitive when case matters, case-insensitive for general list cleanup.

How does sorting by line length work?

Lines are compared by their character count (including spaces). 'Shortest first' sorts from the fewest characters to the most. 'Longest first' reverses that order. Lines with the same length retain their original relative order.

Does the shuffle option produce truly random results?

The shuffle uses the Fisher-Yates algorithm for unbiased randomization. Each permutation of lines is equally likely. Perfect for random selection, drawing winners, or mixing up list order.

Can I undo an operation?

The tool processes in-place on your current text. We recommend keeping a backup of your original text, or using the sample button first to test the behavior before processing important data.

Is my text sent to a server?

No. All sorting, deduplication, and text processing happens entirely in your browser using JavaScript. Your text is never uploaded, stored, or transmitted anywhere.
