Frequently asked questions
Can I use regex capture groups?
Yes. Enable regex mode and use $1, $2 etc. in the replacement to reference capture groups from the pattern.
What does whole-word matching do?
It only matches when the search term is bounded by non-word characters. "cat" won't match inside "concatenate".
Is there a size limit?
The tool handles texts up to about 1 MB. Very large documents may take a moment.
