When to Use Find & Replace

Find and replace is essential for bulk text editing. Instead of manually changing 200 instances of "colour" to "color", find-and-replace does it instantly. This saves hours on repetitive edits.

Regex mode enables powerful pattern-based replacement. Example: Replace all 10-digit phone numbers with a formatted version, or convert dates from MM/DD/YYYY to YYYY-MM-DD format. Whole word matching prevents accidental partial replacements (replacing "cat" won't affect "category").

Use cases: Converting British to American spelling across documents, updating brand names in marketing copy, reformatting data exports, sanitizing sensitive information before sharing, and refactoring code variable names across large files.
