Can I use regular expressions in the Find field?

Yes. Enable the "Regex" toggle to treat the Find field as a regular expression. You can use any valid JavaScript regular expression syntax, including capture groups and backreferences in the Replace field.

How do I use capture groups in the replacement?

When regex mode is on, use $1, $2, etc. in the Replace field to reference capture groups from your pattern. For example, if your pattern is (\w+)\s(\w+), the replacement $2 $1 would swap the two words.

How many replacements can it make at once?

There is no built-in limit. The tool replaces all occurrences throughout the entire input in a single pass when "Replace All" is enabled.

Is the find case-sensitive by default?

Yes, by default the search is case-sensitive. Enable the "Ignore case" option to match regardless of capitalisation.
