Text Cleaner

How Text Cleaner works

Remove duplicate lines, blank lines, extra spaces, tabs, HTML tags and line breaks from any text instantly. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

Four cleanup passes

Duplicate lines, empty lines, extra spaces and leading/trailing whitespace each have their own switch, all on by default. That combination handles the most common mess: text copied out of a PDF or a web page with a blank line between every line and double spaces inside sentences.

Order matters — de-duplicating before removing blank lines keeps meaningful blank lines out of the comparison.

What “duplicate” means here

Two lines are duplicates when they are identical after trimming. Case is significant, so “Apple” and “apple” both survive. For a case-insensitive dedupe, convert the case first, then clean.

When not to clean

Code, poetry and anything where indentation carries meaning. Removing blank lines from Python breaks nothing, but collapsing spaces inside a string literal does. Clean a copy, not the original.
