Text Line Tools
Remove duplicate or blank lines, trim, sort and reverse — all in one pass
What each operation guarantees
- Dedupe keeps first occurrences in original order — sorting stays a separate explicit step.
- Trim and empty-line removal run before dedupe so invisible whitespace cannot pose as unique lines.
- Reverse, sort and numbering touch line order only — no line content is ever rewritten.
The smallest toolkit that fixes messy lists
Cleanup in one pass
Tick remove duplicates, drop blank lines and trim each line, then layer on alphabetical sorting or a full reversal — every operation runs together on the same input, in one click.
First stays first
When a list contains repeated lines, only the first occurrence survives — the order of your remaining entries is untouched, so ranked lists and sequences keep their meaning.
Take the result with you
Line counts before and after the pass sit above each box, and the finished list copies to the clipboard or downloads as a .txt file ready for a spreadsheet import.
Frequently asked questions
In what order are the options applied?
Trim, then remove blank lines, then remove duplicates, then sort, then reverse — in that fixed order, so the result is predictable no matter which combination you check.
Does 'remove duplicates' keep the first or last occurrence?
The first occurrence of each line is kept; later repeats are dropped.
Is there a line limit?
No hard limit — it runs entirely in your browser, so very large pastes are only limited by your device's memory.

What Are Text Line Tools?
Text that arrives as lines — CSV exports, server logs, copied lists, subtitle files — is rarely ready to use as-is. Empty lines, duplicates, stray spaces and scrambled ordering all get in the way of pasting it somewhere clean. Text Line Tools cleans up such content line by line: you tick the operations you need and run them together in a single pass, instead of opening a spreadsheet or writing a script every time. Anyone who handles exported lists — marketers, developers, editors, researchers — will find a recurring use for it. A single pass handles a pasted list of any size, and the output is ready to paste straight into a spreadsheet, a ticket or a new file.

- Flipping a ranked list into reverse order
All processing happens locally in your browser; the pasted text is never uploaded, so you can clean confidential data as freely as public lists.
