§ 02 · what you can do
One editor, every text chore.
Sort & reorder linesAlphabetical A→Z or Z→A, true numeric sort, reverse, or shuffle — one click each.
Dedupe & cleanRemove duplicate lines, strip empty lines, trim whitespace, and collapse runs of spaces or blank lines.
Change caseUPPERCASE, lowercase, Title Case or Sentence case — Unicode-aware, works on names and accents.
Find & replace with regexPlain or regular-expression search across the whole document, with an optional case-insensitive match.
Number, prefix & suffixAdd padded line numbers, or wrap every line with your own prefix and suffix text.
Join, split & undoJoin lines with any separator, split on any delimiter (incl. \t), then undo up to 50 steps or reset to your original.
§ 03 · how to use it
Four steps, no manual.
- Paste or type your lines or text into the editor. Nothing leaves your browser.
- Click an operation from the panel — sort, dedupe, change case, find & replace, number, affix, join or split.
- Stack operations as many times as you like; use Undo to step back or Reset to return to your first input.
- Copy or download the cleaned result as a .txt file.
§ 04 · faq
Frequently asked questions.
Is the Text Cleaner free?
Yes — completely free for everyone. No sign-up, no account and no usage limits.
Is it private? Is my text uploaded anywhere?
No upload, ever. Every operation runs in your browser on your own device — your text never leaves your computer and nothing is sent to a server.
Does it work offline?
Yes — once the page has loaded, every operation works without a connection, because all the logic runs locally in JavaScript.
How does find & replace with regex work?
Leave the Regex box unchecked for a plain text search, or tick it to use a JavaScript regular expression — capture groups like $1 work in the replacement. Ignore case is on by default; untick it for an exact-case match.
Can I undo an operation I didn't mean to run?
Yes. Undo steps back through your last 50 operations, and Reset restores the very first text you entered this session — so you can experiment freely.
How do I split on a tab or newline?
Type \t in the Split-by box for a tab, or \n for a newline. The same escapes work in the Join-with box, so you can join lines with tabs to build TSV.
