Frequently Asked Questions
What is natural sort order and how does it differ from standard alphabetical sort?
Standard alphabetical (lexicographical) sorting orders characters by ASCII/Unicode values, which places 'file10.txt' before 'file2.txt' because '1' comes before '2'. Natural sort order parses embedded numeric substrings as numbers, correctly ordering 'file2.txt' before 'file10.txt'.
Can I sort lines by character length?
Yes. You can sort lines in ascending order (shortest lines first) or descending order (longest lines first), which is helpful for formatting poetry, keyword clustering, and visual text alignment.
How does the tool handle leading whitespace and empty lines?
You can enable options to trim leading/trailing whitespace before sorting and automatically strip empty or whitespace-only lines from the final output.
Can I reverse or randomly shuffle an existing list?
Yes. The tool includes a reverse order toggle and a Fisher-Yates random line shuffle feature to randomize lists, contest entries, or test datasets.
