About Find & Replace

Case Sensitivity

Toggle case matching to distinguish between "Hello" and "hello". Useful for code identifiers and proper noun replacements.

Whole Word

Match only complete words — searching "cat" won't match "concatenate". Uses word boundaries (\b) internally to isolate exact word matches.

Regex Mode

Enable full regular expression support. Use patterns like \d+ for numbers, [A-Z]+ for uppercase, or (word1|word2) to match multiple terms at once.

Multi-Rule

Apply multiple find-replace rules in sequence. Perfect for bulk text normalization, code refactoring, or cleaning CSV/TSV data in one step.
