Expert Q&A
How does "Trim Whitespace" work?
Trimming whitespace removes any spaces or tabs at the beginning and end of each line. This is crucial for identifying duplicates that look identical but have accidental hidden spaces.
Is there a limit on the number of lines?
Our tool is highly optimized for performance and can handle tens of thousands of lines easily. Since it runs in your browser, the limit depends on your device's memory, but it's typically more than enough for any standard list.
Can I reverse the sorting?
Currently, the "Sort Alphabetically" option provides standard A-Z sorting. For more complex sorting needs, you can use our dedicated "Sort Text" tool which offers multiple advanced sorting algorithms.
