What does the Sort, Deduplicate, and Clean Lines do?
Use this tool when you need a browser utility that performs repeatable list cleanup without a spreadsheet. It accepts one text value per line and returns sorted, reversed, trimmed, or unique lines. Results are deterministic for the same input except where cryptographic randomness, current time, or a live provider response is part of the task.
Preserve order or normalize the list?
Use Remove duplicates to keep the first exact occurrence in the existing order. Use Sort and deduplicate when trimming, blank removal, and a new natural sort order are acceptable.
How do you use it?
- Paste one value per line into Input.
- Choose a sort, deduplication, reverse, or trim operation.
- Inspect the resulting order and exact duplicate policy, then copy or download the lines.
Worked example

pearSort and deduplicate trims lines, removes blanks, keeps exact unique values, and applies locale-aware natural sorting.
Common errors and fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Remove duplicates keeps values that differ only by case or spaces. | Remove duplicates compares exact line strings. | Choose Sort and deduplicate to trim values first, or normalize case with Case Converter before deduplication. |
| The order differs from a byte-sorted command-line result. | This page uses Intl.Collator with numeric ordering and base sensitivity. | Use a byte-order tool when a protocol or reproducible build requires code-unit ordering. |
Important behavior of Line Tools
Case-insensitive natural sorting may differ from byte-order sorting used by command-line tools.

Frequently asked questions about Line Tools
Does the Line Tools upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the Line Tools accept?
It accepts one text value per line. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the Line Tools produce?
It produces sorted, reversed, trimmed, or unique lines. Copy and download controls appear when the output format supports them.
What limitation should I know?
Case-insensitive natural sorting may differ from byte-order sorting used by command-line tools.
What changed?
Added Natural sorting, Stable deduplication, Blank-line removal, Reverse order, responsive controls, explicit runtime disclosure, and tested browser output.
