§ 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.
