Line Tools FAQ
Common questions about duplicate detection, natural sorting, privacy, and export behavior.
Does Line Tools upload my list?
No. Line Tools processes text locally in your browser and does not upload pasted lines or generated output.
How are duplicate lines detected?
Duplicate detection can use the exact line, trimmed line, case-insensitive line, or both trim and case-insensitive matching depending on your options.
Can Line Tools sort item 2 before item 10?
Yes. Enable natural number sorting, then use A-Z or Z-A sorting for mixed text and numbers.
Can I download the result?
Yes. You can copy the processed output or download it as a .txt file.
