Why Use an Online Find & Replace Tool?
Most text editors have Find & Replace, but using a dedicated online tool gives you extra flexibility — no software needed, works on any device, handles large pastes, and outputs results directly in your browser without modifying any local files.
Common Use Cases
- Bulk content editing: Replace a brand name, product, or person's name throughout a long document.
- Code refactoring: Rename a variable or function across a code snippet.
- Data cleaning: Replace inconsistent formatting in CSV data (e.g., replace semicolons with commas).
- Template filling: Replace placeholders like
[NAME]or[DATE]with real values. - URL updating: Replace old domain names with new ones across a list of links.
Find & Replace Modes
- Plain text: Simple exact-match replacement. "cat" replaces every occurrence of "cat".
- Case-sensitive: Only replaces exact case matches. "Cat" won't replace "cat".
- Case-insensitive: Replaces "CAT", "cat", "Cat", and all variations.
- Whole word only: "cat" won't match "catalog" or "concatenate".
- Regex mode: Use regular expressions for powerful pattern matching.

Absolutely. For basic replacements, just use plain text mode. When you're ready to explore regex, start with simple patterns like \d (any digit) and \s (any whitespace).
