Many replacements in one go
Instead of running find-and-replace again and again, write all your rules in the list — one per line — and they're applied from top to bottom. The arrow can be →, ->, => or a tab, so you can paste two columns straight from a spreadsheet.
- Ignore case — “Cat” and “cat” both match.
- Whole words only — “cat” won't match inside “category”. Works with letters from any language.
- Regular expressions — use patterns such as
\d+, and$1,$2in the replacement for captured groups.\nand\tin the replacement insert a line break and tab.
The summary shows how many times each rule matched, so you can spot rules that did nothing.
Examples
- Mask phone numbers:
(\d{4})-(\d{4}) → ****-$2with regular expressions on. - Delete a word: write
word →with nothing after the arrow.
