Find and Replace FAQ
How does find and replace work?
Type the text you want to find and the text to replace it with. The result updates live in the output panel, with a count of how many matches were found and replaced. Toggle case-sensitivity or regex mode for more control.
Is the find and replace tool free?
Yes — completely free, no signup, no login, no limits on text length.
What is regex mode?
Regex (regular expression) mode lets you match patterns instead of literal text. For example, \d+ matches any sequence of digits, and \s matches whitespace. When regex mode is off, your search text is matched literally (special characters are escaped automatically).
Is my text private?
Yes. All find-and-replace happens in your browser. Nothing is uploaded, logged, or tracked.
Can I do case-sensitive replacement?
Yes — toggle 'Case-sensitive' on. When off, the search matches regardless of capitalization (e.g., 'Apple' and 'apple' both match).
Does it work on large documents?
Yes. The tool handles documents of tens of thousands of words instantly, since all processing happens locally in your browser.
Can I use capture groups in regex replacements?
Yes. In regex mode you can reference capture groups in the replacement using $1, $2, etc. For example, find (\w+)@(\w+) and replace with $2.$1 to swap around an email-like pattern.
