What is find and replace?
Renaming a function across a pasted file, or fixing a typo that appears forty times? Enter the search term and its replacement, and every match swaps out with a running count of replacements. Regex mode unlocks JavaScript patterns with capture groups, so replacing “(\d+)px” with “$1rem” converts units in bulk. Matching happens on your own machine, which makes it safe for config files and credentials.

Frequently asked questions
Does it support regular expressions?
Yes. Turn on the regex toggle and the find field accepts any JavaScript pattern. Capture groups carry into the replacement, so finding “(\w+)@example.com” and replacing with “[email protected]” migrates a whole list of addresses.
How many matches can it replace?
All of them, when “replace all” is on, and the counter reports the exact number. Switch it off to change only the first hit, which is safer for one-off fixes.
What happens with an invalid regex?
An unparseable pattern produces an error and leaves your text untouched. Fix the pattern and the replacement re-runs against the original input.
