Frequently asked questions
How does regex mode work?
Turn on regex mode and your "find" text is treated as a regular expression — for example \d+ matches any number. You can even use capture groups like (\w+)@(\w+) and reference them in the replacement with $1, $2. Invalid patterns show a friendly error instead of breaking.
What does whole-word matching do?
It only matches your find text when it stands alone as a word. Finding "cat" won't touch "catalog" or "concatenate" — only "cat" itself.
Can I undo a replacement?
Yes. Every Replace all is saved to a history, and the Undo button steps back through your changes one at a time.
Is my text uploaded anywhere?
No. Everything happens in your browser with JavaScript. Your text never leaves your device.
Is there a text length limit?
The amount of input this tool can handle depends on available browser memory and the limits shown by the controls. Larger jobs can take longer or fail; try a smaller input if the page becomes slow.
