Text Tools Box
Free online text toolbox: remove duplicate or empty lines, trim, sort, change case, reverse, number lines, and live count of characters, words, lines and bytes. Runs in your browser.
How to use
What it does
The text toolbox bundles the most common cleanup operations into one-click buttons: dedupe lines, drop empty lines, trim leading/trailing spaces per line, sort ascending/descending, reverse line order, convert to upper/lower/title case, strip all spaces and control characters, and add or remove line numbers. Each click acts on the current text and keeps a history so you can undo.
A live stats bar shows character, word, line and UTF-8 byte counts at all times. Everything runs in your browser — no text is uploaded.
Example
Paste a few repeated lines:
banana
apple
banana
cherry
Click "Dedupe lines" and you get:
banana
apple
cherryThen "Sort (asc)" produces alphabetical output.
